officials have now asked for f-16 fighter jets. how does it end? joining me now is former secretary and head of the cia robert gates who served under eight u.s. presidents of both parties. good to see you. >> thank you. >> we will lower the temperature here a little bit. i want to start with something you wrote with secretary condoleezza rice about two weeks ago. about the war right now. we are convinced that putin believes time is on his side. that he can wear down the ukrainians and that the u.s. and european unity and support for ukraine will eventually erode and fracture. to be sure the russian economy and people will suffer as the war continues, but russians have endured far worse. you just saw what i was leading in with. we have -- public support is there, but it's fading. it looked like this week nato support is there, but it could fracture. how much time does the west and ukraine have here?
