I don't know if you noticed, but a lot of shit has happened in the world since WWII. After WWII, the US got it into their heads that they were the moral compass for the rest of the world. Hence, Korea, Vietnam, and now the Middle East. Hitler wanted to rule the world. The US just wants everyone to have a democracy.
Korea was a waste of time, but at least the US was only involved for 3 years.
Vietnam was absolutely horrible and severely split our country in two. The Middle East situation is headed in the same direction.
I would've fought in WW2 because every single person's life in the world was at stake. That's why it was called a World War. I wouldn't have fought in Vietnam because that was just a political war. Remember, the US was trying to stop the spread of communism? In the first Persian Gulf War, I was 18 years old and you can bet Uncle Sam wanted me to sign up. No fuckin' chance! I ain't fightin for oil! Now we're allegedly fighting to stop terrorism. Terrorism is horrible, but what the fuck are we doing in Iraq? If you're so pro-war, why didn't you go off and fight? The US could use more folks like you. Haven't you heard, Uncle Sam's having a tough time recruiting folks to go off and fight? Unless of course, you're gay. Then Uncle Sam doesn't want you. You might make a pass at one of the boys that's in a foxhole with you.
You're grandpa wouldn't be fighting in today's war and he wouldn't want you fighting in it either.
