because NATO and Russia have always been very smart in their actions . aggressive enough to prove a point but not enough to cause a major war .
the whole point is to basically say " i could if i wanted " . no side would EVER fire a shot at eachother …that was until turkey broke that rule of an air incursion lasting . what was it 17 seconds ? then cry to NATO for help .
there was no need to fire at the russian jet . by all means scramble show your teeth but dont fire unless you absolutely have too .
turkey shot it down because the russians were bombing their terrorist friends , thats it .
russia has buzzed the US ship because its in their back yard and they dont like it . much like the US wouldnt like it if a russian destroyer entered the gulf of mexico . much like we dont like russian fleets in the english channel and when they come we escort them all the way .
