There is an obvious discrepancy in size and power between Russia and Ukraine. Joe Biden sought to eliminate, or at least reduce, the discrepancy by providing Ukraine with arms and money in an effort to maintain Ukraine’s independence. Trump, on the other hand, clearly has no desire to remain Ukraine’s ally, but he wants an end to the war. How can he get it?
He has three options. First, he can offer his services as a mediator–an honest broker with no preference between the two sides. Second, he can attempt to impose a reasonably fair settlement of his choice on the parties. Third, he can openly switch sides, support Russia, and force Ukraine and its European allies to surrender in exchange for whatever crumbs of autonomy Putin will accept.
The second option won’t work because the only way Trump can impose his will on Putin is to threaten escalation; it is obvious he has no intention of doing that. As a result, any intervention on his part will be completely one-sided. Both the first and the third alternative could well mean the end of NATO, since the Europeans won’t agree to abandon Ukraine. I think that is where we are headed.
