The only “deal” Trump would ever cook up for his pal Putin is a complete control and ownership of Ukraine, as well as whatever other land Putin happened to be interested in.
That was a goal. As was undermining and destroying all the global institutions that arose under the sponsorship of the United States after WWII. NATO, the EU, the UN, the G-7, the G-20 etc.
Ukraine was to be the first domino in an overall plan to reinstate the Iron Curtain, and put all of Eastern Europe under Moscow’s thumb.
How do we know this? Because Vladimir Putin said so.
And they helped install a man they owned to insure that the US would quit the world stage on Moscow’s terms.
And Putin was successful to a degree. Trump did his level best to betray the legacy of Churchill and Roosevelt. Had he continued, he might have succeeded. He did manage to make the Office of President of the United States temporarily irrelevant on the world stage. Just what Moscow wanted.
Putin made the mistake of believing that trump’s coup attempt had so weakened the American spirit, that it would roll over when the Red Army crossed the Ukrainian frontier. Trump supported him. He still does. He has Fox News in his pocket too. And right wing media is still singing along.
Trump has nothing to offer Putin anymore.
With a lot of help, both of them can be relegated to the past.
