Putin's Requests Granted By Trump So Far...
Despite some buyer's remorse over Trump being a big enough idiot to get caught doing this stuff, I don't think Putin regrets expending so much energy on buying a U.S. President.
So far, Trump has delivered on the following:
1. Lift Obama sanctions on Russia over the invasion of Crimea. (Foiled by the FBI, but at least he tried.)
2. Lift Obama sanctions on specific Russians over interference in 2016 election, and give them their houses back. (Again, foiled by FBI, Rosenstein etc., but again, he tried.)
3. Weaken NATO (Delivered!)
4. Break apart the E.U. (Delivered!)
5. Remove U.S. troops from Syria (Delivering!)
6. Destroy faith of U.S. citizens in their own government. Particularly their intelligence agencies. (Delivered!)
7. Destroy faith of other world democracies in the United States as a leader. (Delivered!)
8. Suppress and intimidate the United States press, so that they will no longer be effective at shining spotlight on large scale criminal activities by plutocrats. (Delivered!)
9. Fracture the U.S. population over wedge issues, to the point where they can no longer elect an effective government. (Delivered!)
Given that Putin has gotten most of what he wanted out of Trump, at this point there's no reason to keep him. I think the Russians will leak some dirt on Trump fairly soon, and try their luck with Pence.
