Again, both actions you cite were reactions to US meddling in the region in the first place.
The fact Trump hasn't threatened any new invasions is already an improvement.
PS. Do you know who Mikheil Saakashvili is, what he did, where he is now, and why he's exiled from his own country? And have you seen Victor Yushchenko's face recently, what it looks like? The answers to both of these questions give a lot of insight into US actions in the region.
Right -- the several thousand army and special forces troops that Putin has since openly acknowledged sending there to size buildings and other strategic checkpoints were just out on vacation.
Either way -- the main point is (and presumably you do know this), the leased military base at Sevastopol != the Crimean peninsula.
Trump would improve relations with Russia.
Also, I wouldn't call what Obama did sable rattling. Russia did invade several countries in the last years (Georgia, Ukraine, and maybe I'm missing one more?). If you don't have a good response for that, then how can you be trusted to defend your other allies (Poland, etc.)
