Trump knows this, Putin knows this, the Poles know this, we know this.
This is nothing but some feel-tough ego masterbation for the mulatto traitor faggot who's been squatting @ 1600 for these past eight miserable years.
Something else DJT and Putin know - and likely Poles as well - Russia’s war policy is: if attacked with conventional weapons, they will respond with nuclear.
So any putative war 0bama starts will go nuclear at once. All bets are off here.
All S-300/400/500 systems are nuclear capable ... Russia has long had 1.0 - 0.5kt warheads for ICBM defense.
