FOREIGN POLICY: The Pinprick President: Barack Obama needs to go to war with the Islamic State, or it will go to war with America. I generally favor a nip-it-in-the-bud strategy — just think how much better off we’d be if Bill Clinton had seized any of his several opportunities to kill or seize Osama bin Laden — but I have to say my confidence in Obama’s ability to carry out anything much bigger than pinpricks is severely limited.
