Putin has pissed Trump off. How can the war be stopped now?

Putin has pissed Trump off. Not irritated, not disappointed, but pissed him off, in his own words. It was only recently that Trump said Putin was "someone who wants peace" – what happened? Exactly what I recently said would happen: Putin is a gangster. And like any gangster, he interprets concessions as weakness. He doesn't negotiate, he stalls for time and raises the stakes. But this game has a deadline – and it's getting close. How much time does Trump have left? How long is Putin ready to haggle? And who truly has the levers necessary to stop the war?
