“I, a proud member of the U.S. military, won’t obey illegal orders to attack our allies.”

Yeah. Pretending to be honorable as part of the worlds largest terrorist organization. These dumb Joes are still riding the win from their great grandpa in WW2.

It's hard to get out of the brainwashing. I was Navy and honestly it was the direct exposure to what we were doing that finally got me to pull my head out of my ass and move left. When you grow up in it, and it's all you know, getting past the propaganda is tough.

To be fair many also rebelled and organised against the US war against Vietnam while stationed there or at home on US soil. One of the critical stages of the anti-war movement was the appearance of the anti-war GIs at anti-war rallies linking the armed forces and the anti-war movement. This represented one of the biggest rebellions in any armed forces since the Russian revolution and posed a real threat to the adminstration. It's also one of the main reasons the US withdrew from Vietnam. They had to find a way to head off this movement becoming even more radical and making more links with anti-war, workers and revolutionary organising.

There is a great doco about this called Sir! No Sir! from 2004/5.
