Maybe congresses best move is to name the Donetsk People’s Republic (DNR) a terrorist organization, which would make Russia a state sponsor of terrorism....AND proclaim the Russian govt is a terrorist organization if it is proved that active duty Russian military personnel were manning that BUK missile unit or there was any Russian command structure regarding that BUK. US intel may already have proof of that.
That would be the best move — but of course, Pooty Poot would go right on doing what he was doing before, and his bootlickers would continue to support him, even on FR.
