The only important response is the majority opposing a pullout. That pertains to the current decision at hand.
I have some confidence that the public realize that pulling out of the situation would be a disaster. I also think that they're frustrated because it's sooooo obvious that the suits in Washington are jerking around and need to apply great power and end this thing. That they won't is what will force a pullout, through public frustration with their dilletance (is that a word in English? It's been so long since I studied French).
I fear that dragging the mess out (along with economic problems and the Mexicans) will also open the White House door for the Witch Queen, sap our strength viz a viz the Chinese, and God knows what else.
