mentioned that -- excuse me -- you mentioned the united states opposed turkey's incursion into northern syria and erdogan always want add safe zone here. what concessions did you chi actually get from president erdogan and terms that they would comply and said they wouldn't do before and with the u.s. sanction in terms with them then moving south how do you address critics that call this second abandonment from the kurds? >> you'll see from the agreement itself what concessions were made. president trump in his telephone call with president erdogan earlier this week and in the directive that he gave us to deliver, was very clear that he, he wanted a cease-fire. he wanted to stop the violence.
