In this particular case talking to Putin makes no sense, he only understands force. Talking makes sense much earlier but even then actions are more important.

Take for example the Middle East: there is no way you could solve the problem by talking, especially now. Palestinians believe this is their soil, the Israeli think otherwise, the former send rockets, the latter shoot these rockets and send their pilots, the pilots see the attackers tied to children on the roofs... This has gone too far over the years.
