Germany and Russia, for the last century, have had the best reputations on weapons technology. The weapons that are developed in the states are based off ideals and models from Germany going all the way back to the Nazis. Russian missile technology is FAR superior to US, the much feared S400 missile system was conceived during the mid 1980s and it beats out the antique patriot systems by a wide margin. I'm just giving one example. It's very easy for regular citizens to be so dismissive but talk to actual Colonels, Generals, etc and they'll tell you different.. It would have to be entirely preemptive if we needed to strike Russia and even a move like that could fail.
