i feel confident in saying that sigar's work as well as some of the other literature out there that talks about what has worked and hasn't worked in afghanistan is very much a part of the recommendations we made to secretary mattis and the president. >> also on that one, the july sigar report has a 21% increase in security incidents of last quarter of march 2017 and increase from the same period last year. what does this uptick in the security incidents tell us about the security situation overall and how are we shaping our strategy going forward in light of these particular figures? you can answer that quickly, time has elapsed. >> sure. will tell you i don't think any of us are satisfied where security in afghanistan has been in 2016 and 2017 although 2017 is slightly better than 2016. the reason why we believe those incidents have occurred because the afghan forces haven't had the wherewithal for their mission. we focused where they have fallen short of the mark and security aviation and level needed. >> thank you. >> mr. chairman, secretary mattis and general dunford thank you for joi
