He's not talking about the Marines. He's talking about the two socialist frat boys that keep saying over and over and over and over that islam is the Religion of Peace. Not once has either man stated publicly that islam is indeed a religious political philosophy hell bent on taking over the world and forcing their style of ignorance on the rest of us. The Marines know this, but it's not their place to shout it from the roof tops.
Who sent in a huge armed force to take care of business. An honest person would not ignore what they have actually done.
Just as a practical matter, you're not going to make any progress at all, going into a place like Iraq and declaring a holy war. That would be immensely stupid. But then, keyboard kommandos are not particularly bright, when it comes to thinking beyond their own dislikes.
