My sympathies to the families of the passengers and crew of the downed plane. Let’s not jump into another war please.
We don’t need to start another war.
Or I should say we would not have needed to if we had done the right thing to begin with.
Putin is not stupid. He will not directly attack the US or US troops.
Had we stationed troops and assets in the Ukraine, Poland, etc, as we have in Germany, Korea, etc., nothing would have happened.
It has been said many times that nature abhors a vacuum.
So do dictators.
