People should remember the Iraq war and especially the build-up to it. Debates were silenced by the rallying call to "Support our troops!" You couldn't claim that the war was a pointless hunt for oil engineered by the oil companies. Because that implied that the "war moms," those who let their sons enlist and fight the stupid war in Iraq, were doing something wrong. Telling it how it was, that whoever travels half-way cross the world to participate in a war against a people they should have no beef with, is committing state-sanctioned murder, was not allowed. I know that is polarizing, but polarizing is whatever a lot of people disagree with. It doesn't mean that it is factually incorrect.
So the next time the US rallies the dogs of war, remember Iraq and what made that war possible. Because it will happen again. When Trump, or his successor, decides that "something has to be done" about North Korea, Iran or Syria, do break the decorum. Don't allow disagreement to become taboo because then history will repeat itself.
