We can re-litigate Bush Junior’s lies, but this is not the time. That was misdirection after 9/11 and should have been directed at Bush family friends, the Saudis, not Iraq. But that is old news. Here we Assad using chemical weapons. We cannot ignore that and allow them become acceptable. Otherwise, the next chemical attack could be in New York or San Francisco or any city in the US.
I tend to think that without this sort of action, eventually Israel gets hit with chem or bio weapons, sooner than us, and THAT (Israel getting WMD’d) definitely could lead to a “WW3” (or at least a significant nuclear exchange) type scenario.
