If more Americans are killed on American soil by the hands of Shia radicals or IRCG supporters the American bloodlust for war will rise. A critical feature of America that is often forgotten by both our allies and adversaries is that despite our colonial roots, we are not Europeans. We will have a very low tolerance for the deaths of Americans. If the FBI is correct, we have hundreds of sleeper cells active in the U.S. Another Texas-style shooting and I suspect even anti-ICE liberals will change their position.
