The attitude toward wars displayed by countries that have never in living memory fought one on their own soil is frankly terrifying in its stupidity, though.
The last military power that was stupid enough to put on uniforms and march infantry onto American soil was the Confederate States of America. How'd it go for them?
America's attitude toward war is "If we're going to fight, it's gonna happen in your face, not mine."
I'd give your comment the tiniest but if credence if you had the data to quantify it, but 2/3 of your examples don't think that kind of information should be shared.
Basically, you're forming an opinion based on incomplete data.
