jane:s welcome to our view public television in the u.s. and around the globe. ukraine's parliament has voted to impose martialaw in 10 provinces bordering russia, a day after a russian ship seized three ukrainian vessels off the coast of crimea. moscow annexed the ter in 2014, and both sides blame each other for the float. -- for the latest flareup. western countries including t m u.s. condemncow's actions. the bbc's steve rosenberg has the latest. steve: off the coast of crimea, russian border guas on collision course with the ukrainian navy. the russians target a tugbt. the hint is less than subtle.r,

lateussian forces shoot at and then seize the target and two other ukrainian vessels.en this appy a mayday from ukrainian sailor as the russians storm his boat. a russian replies. steve: the vessels were towed to russian-controlled crimea. 23 ukrainian servicemen have been detned. after the dramas at sea, political battles over who is responsible. moscow's reaction, don't blame russia. officials here areresenting what happened as ukrainian provocation in russian territorial waters. ukraine rejects that and insts this was an act of aggression against its neighbors. -- it's navy. oon the streetsf kiev, they agree.

"death to russia!" he shouts. protests and pyrotechnics outside the russian embassy.pr ukraine'ident, petro poroshenko, called for 30 days of martial law in parts of the country. meanwhile, at the united nations, this warning for moscow. ambass states will maintain its crimea-related sanctions against russia. further russian escalation of this kind will make matters worse. steve: to some, the incident is a reminder of how dangerous the russia-ukraine conict is. >> the war continues to be live, and the war could escalate aty an moment while endangering the relationship between russia and the west. steve: at sea and in the sky, russia has sent a clear messagea to ukrai the west, don't mess with moscow. steve rosenberg, bbc news,

moscow. jane: for with michael carpenter, senior director of the penn den center for diplomacy and global engagement. how bia crisis is this? michael: i think it is a significant escalation of the war between russia and ukraine just on the fact that russia has rammed a ukraini ship and boarded two other naval vessels and seized the assets and held the sales captive. it isnn this creepingation and it logically leads towards further incident. i think russia's goal is to blockade the ukrainian ports. to that extent this is very serious. jane: is this a precursor to something else? michael: i think this is a part of a series of small steps that taken together are designed to blockade the ports and to harass commercial traffic in advance of

ukraine's presidential elections. russia wants to apply economic pressure as well as military pressure on ukraine. that is their end goal, to squeeze the ukrainn state and make them feel vulnerable. jane: a lot of condemnation at the united nations, but what can the international community actually do? michael: there have been rdstiffly- statements but not a lot of action. we will have to see in the coming days. there is a lot that the united ates and its allies can do. among them are increasing naval presence in the black sea amongs naps.in another is to help ukraine oral byits seaitt providing defensive s, etelligence and surveilla systems, ground-based anti-ship missiles. but also more offensively, in terms of a counterpunc sanctions on russia. not necessarily in response to

this incident, but in response to russia's 4.5-year war against ukraine. those sanctions have not been strong enough thus far. jane: w isn't russia listening? why would more sanctions work? michae because the sanctions the western countries imposed on russia are wk, they are thin uel. we have no blocking sanctions on major russian banks. what we have is restrictions on the financing of new debt and equities by financial institutions. p that is a rathhetic, weak measur could do and what we have done in the past when trying to compel iran to come to the table. jane: who should be le this? there is a lot of concern about u.s. policy towards russia, not just about ukraine but generally. michae i saw ambassador nikki haley at the u.n. called for the normandy forma-- germany, france, ukraine, and russia to resolve this. i think that is a huge mistake.

but -- i think the resolution of the conflict, if there is to be one, has to be led by the united states together with european allies -- france and germany certainly deserve a seat at the table -- but this has to be multilateral diplomacy backed up by leverage. frankly, only the united states can do that. jane: michael carpenter, as usual, thank you for joining me. michael: my pleasure. jane: president trump has defended the use of tear gas against migrants trying to cross the border from mexico. mr. trump said it was necessary because officers were being rushed by very tough people. humarights groups say many o those seeking to enter the u.s. were women and children. mexican authorities say they are ing some of those involv in sunday's clashes. the bbc's will grants at the border and he sent this report. will: when the poorest peoplin the americas try to force their way into its richest country and met with resistance, riot police, and tear gas. what began as a peaceful protest

over their asylum claims soon descended into a scramble towards the bord. the u.s. and mexico closed the crossing and pushed them back. the caravan awoke this morning d by the violence, which prompted a much greater police presence. some had been deported for taking part. others have been caught with their children in the plumes of thar gas fired at them fro u.s. side of the border. >> we were pushed and pulled, kicked by the police. my wife was hit and so were the kids. and for what? we are not criminals. we are not trump thinks we are. we are for working people. will: it came as little surprise some attempted to cross stuck in legal limbo with no sign of movement, people are tigrowing impat. conditions in tijuana are worsening fast. fothis is the queubreakfast. it lasts for hours, and for mane

it will benly meal they receive all day. president trump, however, isn't sympathetic to such complaints. "the migrants were stone cold criminals," he said, and warned he might close the border permanently. jeopardizing a billion dollars a day in cross-border trade seems unlikely, but these short uaclosures are affecting t. it is a city that depends on tourism, and traders like francisco arfeeling the pinch. "things have been much quieter this week," he says, blaming the slowdown on the mithants. most icaravan don't want to cause problems. as temperatures drop itijuana, they are facing christmas in the open air, camped out by the border wall, and they know another attempt ul run across see them deported with the a u.eady in sight. will grant, bbc news, tijuana. jane: for more on this and some of the presidents other comments f today, i was joined a brme

ago by reid wilson, correspondent for "the hill." lte president is threatening to close the borderether. what message is he sending, and what does it achieve? reid: the president is committed to using immigration assue to rile up his own base. he believes that is how won in 2016. he believes it was successful for republicans in 2018 despite the fact that the results swed towards democrats. it is his comfort zone as he deals with all the issues taking place in the world. this seems to be the one returns to because it is the one he is most comfortable talking about.ja : and you say a lot of issues he is dealing wit a he hot on his mind today. he is not happy about general motors axing 14,000 jobs and potentially closing five factories. he is threatening them, but is there anything he can actually do? reid: there's not much the u.s. government can do to f company to keep the plant open or open a new one somewhere else. healuggested the head of gen motors might open a new factory

in ohio. that is not the way this economy is moving. these car compans have been saddled by declining demand for small cars, increang demand for large trucks, and those are built in different factoes. it is notpl ssomething the government can do to force the company to do this. the closers will happen in places where president trump won in 2016, w places liren, michigan, and lordstown, ohio, two counties he won after president obama won them twice. it is swing territory, and if president trump promis would bring back the car jobs and was not able to do it, those voters might take it out on him in 2020. jane: you say "might." is there any evidence that the supporters will be persuaded by this, because they have not been over tariffs. reid: they haven't yet.

there is pretty strong evence based on the midterm elections that suburban voters in a lot of these key states where republicans lost u.s. house seats have turned against president trump. his disapproval rating is 60% now. itot hasit that mark for more than a year. this is a president who begins his reelection fight in a tenuous position. let's not forget that he won a couple of key states -- pennsylvania, wisconsin, and ohio -- by 70,000 votes. jane: very briefly, on climatell rtange as he says he does not believe a rey his own administration that points to very serious economic impact. this is a bit of a pattern. he undercuts his own administration all the time. why? reidconstantly. this is a president who comes to office with very firmly held views abouimmigration, about climate change, and about the way things used to be in america, making erica great again. the climate change report is a part of that. this is something that there is scientific consensus on.

there is no serious scientific opposition to the notion that climate change is real and getting worse and caused b humans. but the president is not willing to bend his preconceived notions on that. jane: reid wilson, thanks for idjoining me. thank you. jane: look at some of the day's other news. former trump campaign aideou george papads has failed in a legal attempt to delay his prison sentence. he was convied for lying to federal agents investigating alleged ties between russia and the trump campaign. has facedime minister a barrage of hostile questions in parliament as she continues to promote her brexit deal. the agreement was endorsed by eu lead s on sunday but there appears to be little support in rlment from her own party. a least one million bees suspected to have died of producing in the wine-
