The central front of the war on terror is no longer Iraq. It is not Afghanistan. It is the West, and all lands associated with the West. So the radicals strike Israel, they kill in Sydney, they gun down cartoonists and Jews in Paris, they plan to strike the U.S. Capitol with pipe bombs and rifles.

Such a pattern of destruction ought to force a reevaluation of American strategy. But that has not happened. Instead our response to jihadism has been confusing, contradictory, insipid, self-destructive, and inane…

Only by extinguishing ISIS can the United States begin to reassert its authority and put the jihadists on the defensive. But increasing the number and pace of drone and air strikes will not be enough. The number of U.S. ground forces in Iraq must be dramatically increased, and America seriously must work to remove the cause of the Syrian civil war: the mass murderer Bashar al-Assad, who continues to use chemical weapons, has entered into a de facto alliance with our terrorist adversary, and is reconstituting his nuclear weapons program.
