In my opinion the only relationship between Trump and Putin is that they were both playing each other for their own selfish purposes.
If they parted company, it wasn't because Putin changed his goals. His goals are still steadfast.
It was because someone put a bug in Trump's ear about using a Nobel Peace Prize to further his goals (and do a one-up on Obama) thus, retore the military assistance to Ukraine to stop "all those people from getting killed."
The truth is, Trump never gave a second thought to "all those people getting killed." His real objective was to create an image of a peacekeeper (Stop the War) for the benefit of the Nobel Peace Prize Committee.
Trump has a history of changing course whichever way the wind is blowing, so there's no telling when someone else will put another bug in his ear and we'll see another flip-flop from the King of flip floppers.
One news reel showed him wearing orthopedic shoes now. This is more than "a little" swelling. Congealed blood? No circulation? Black hands?
Sounds like it could get Gangrenous. I wonder how long he's been hiding this weakness.
