If I see a guy with a missing limb or a bad injury I have no problem thanking them for their service. That's a big sacarfice to make.
And look where we are now---Iraq is fucked, Afghanistan is still cracked, Iran is threatening to cut off oil, we've lost crucial tech to them, China has us by the balls economically, our borders are not safe...we have a shitty economy by being baited into two wars, and greedy fucks on wall street.
So, was a limb worth it? Hell no, I'd be mad as hell...
Oh, but we got a US made boogeyman, and now we are looking for another nemesis---we should look in the mirror
