Seems like Putin is going to be a bad bad dog. He has his own pre-conditions to even a cease fire - such as Ukraine not receiving anything during the 30 days (while obviously he will be replenishing the front like crazy).

Also, he wants to keep pushing the full disarmament, recognition of territories under occupation... well, I think Trump and Rubio are about to discover how useless is to talk to Putin. First you need a significant military defeat, then another and then... may be the dog will sit.

All this publicly expressed so it now clear for Trump the degree of "respect" they have for the US.
