This is a strange post where I support Obama. We as Americans are not suited to wars where civilians are cannon fodder. Russia and other nations are held to lower standard. I don't like war in general and it is even worse fighting an enemy with a snuff film mentality.
What has to be done is brutal and beyond our ethos. You beat such a foe by sapping the will of the public. You make support and shelter painful. You make people turn on their neighbors. You level whole neighborhoods. This is quite different from a traditional foe.
ISIS unlike the left is factually correct. As all of the States are colonial constructs the argument for yet another
Arab state is facetious. It always has been a false narrative pretty much a repackaging of old time Jew hatred. It is not fashionable for Ducky to rail about Jews. Thus he turns his maniacal focus on the planets only Jewish state. He does so knowing that Palestine was contrived after Jews into the Sea didn't market well.
Obama is a lame duck and should sit this one out. Let the issue become a campaign issue and let the next President decide.
