Yes. Yes. Increase our defenses, vigilance and counter-attack in a like manner. Your defense of the Russians is interesting.
Disagreed. Obviously. Of course, that's what the Russians would want us to do. Again, whataboutism.
No, I don't. OTOH, I do think that people who bring up US actions during the Cold War but never, ever say a bad word about the USSR and the PRC, are communist sympathizers or lackeys.
