Destroy ISIS, with ground forces if needed. The US was well on its way to achieving a temporary and potentially region-changing victory after the Surge and the Arab Spring, before the president pulled the forces out. Return to the Bush Doctrine and treat states that harbor terrorists as if they are terrorist states themselves. I am under no illusion that this would not be a tremendously costly and deadly effort, but we have little other choice.Put enormous pressure (up to and including military pressure) on allies like Saudi Arabia that consistently fund and support terror. Sunni states need to repudiate the notion of a Sunni caliphate, up to and including by force of arms, if they are to have any expectation of dealing with the United States on any kind of friendly or even neutral basis.Continue to become energy independent (the US is a net exporter now, so little effort is required here except to continue what is already happening). I could go on about the importance of the US understanding that it is fighting a global war against Wahhabism, but those like you would do well to understand that the United States is not Wahhabism's only target. Organizations such as ISIS that want to establish a Sunni caliphate also want to kill or exile all Shia and Sufi Sunni Muslims. They condemn them all as apostates. These Muslims, and even many Sunni Muslims who suffer under Wahhabism's oppression in states like Saudi Arabia and Egypt, are at worst the enemies of our enemy and are at best potentially much more.Wahhabism consistently polls very well in the Arab world. And why wouldn't it -- when a tiny sin against Wahhabist Islam will cost you your hand, tongue, or head?The people beheaded in Saudi Arabia for expressing pedestrian liberties are not our enemies.The slaves of Boko Haram are not our enemies. The victims of Al-Shabaab are not our enemies.And Americans who are followers of the Muslim faith are not our enemies.There is no easy solution to this problem, and the solutions proposed by populist carnival barkers have no value or possibility of actually addressing the problems we face. The solution to the problem is a long-term and exceedingly costly commitment to rooting out and destroying Wahhabism, as the free world rooted out and destroyed Nazism and fascism before it....
