pretty much. Do you really think we'd take our cheeto-stained hands off the keyboard and start shooting at people? I know I'm not ready to get shot for some abstract idea. Sure, I'd maybe spend some time and/or money, but I don't think anyone but the crazies would start shooting.
Besides, I think that shooting back is rarely effective in modern warfare; it's all about 'hearts and minds' these days, not about who can kill more of the other dudes.
It's pretty difficult to invade another country and win any 'hearts and minds' - I mean, no matter how shitty the previous government was, you are a foreign invader.
I think Iran (and Iran's success against the USSR) is a prime example of how 'hearts and minds' is much more important than guns and bombs in modern warfare.
