Russia has still not the means to oppose USA.
Putin didn't (couldn't) react to a Russian airplane shot down by Turkey and one of the crew member murdered by the militian paid by Turkey. No way in my opinion, at this time, Putin/Russia will do something.
Now, more worrying is how Russia will use this for their own purpose. If I was Ukrainian, I would be deeply worried about Trump's wording (national interest).
US president changed, US policy still the same.
