Comment on the difference in foreign policy towards Russia under the Obama and Trump administrations and provide your opinion on Russia's military strength compared to Western forces.
The Russians got a free pass with feckless and weak Obama, but I don't think it will be the same with Trump. 
He's already publicly embarrassed Putin an Lavrov by stating that they were either outplayed by Assad on still having chemical weapons - when Russia was supposed to ensure he didn't - or simply naively stupid. 
The Crimea was clearly invaded by the Russians and stolen. The Ukriane has already been invaded by Russian forces and weapons, but the fight is far from over there. 
The Russian military is no match for Western forces, except for their tank division. Every other part needs major upgrades and with sanctions, money is tight. 
I suppose Putin's next move depends on what corrupt dictator wants to pay him for support to add to the billions he's already collected from corrupt dictators for his support.
That is unpredictable alright, but not in the way you think.
