One of the reasons I refuse to get excited about reports that Trump might be pivoting back to supporting Europe and Ukraine is that they are based often on ephemera. The occasional Trump tweet (always heavily qualified) or even worse the statements of pro-Ukraine Republicans who do not actually speak for Trump.
In reality, what we have is that Trump has established an intimate and regular conduit of discussions with Putin, and moreover is keeping those discussions as confidential as possible by making sure that even other US government actors know nothing about them. In other words, in public he might act like a friend of Europe’s, but in private he is communicating his wishes to be a friend of Putin in a way that gives Putin both a great deal of assurance and a major strategic advantage.
The key figure in this Trump-Putin dialogue is Steve Witkoff, who is Trump’s (and Putin’s) hand picked emissary. I’m sure you know who he is,
a NY real estate developer who has a long-term relationship with Trump. What is interesting is that Putin quickly decided that he wanted to deal only with Witkoff and not with any other US emissary and basically ordered Trump to no longer involve Keith Kellogg in negotiations. You might also remember
Witkoff from the moment when he put his hand on his heart in a sign of devotion as he was meeting with Putin.
