Well, when you start a bogus war in Iraq, yes, you will get a push back from Marines/anyone. Why? Because America has to follow the rules. Meaning don't invade countries on fear induced false pretence. AKA Unlawful orders.

Example...First Iraq war. They just rick rolled Kuwait and looted the country basically. The UN gave permission to liberate Kuwait. So America 'shock and Awww's" for a couple days and the war was over. People, many of them journalists ask "Why don't we go all the way to Baghdad?"

Because our orders was to liberate Kuwait. Not conquer Iraq. Why? Because that's all the U.N. authorised. We didn't want war with half the middle east. That's why Israel didn't run over the other half of Iraq, and draw other countries into the war. 

It would have been unlawful to do anything other than liberate Kuwait.

Unlawful wars make 4 star Generals and 'full bird' Colonels to resign in protest. AKA Second Iraq war. 17 years of war and counting. You have no idea...Seriously.
