So what should the U.S. do? Pretty much what it's been doing in the Obama administration, which has in fact been thinking seriously about Yemen all year and which has quietly been working there in some constructive and some unconstructive ways. It's never as satisfying as a morally pure call to battle, but the administration shouldn't over-react or under-react. Be patient, build intelligence and CT assets, strike against clearly AQ targets when available but only where the civilian costs will be minimal and the rewards high, search out local partners... the usual. But the administration shouldn't fall into the trap of thinking it must "do something" to fend off political harping from the right and end up over-committing... or taking steps which ultimately make the situation worse.Deep breaths, people. Remember what Bin Laden has explicitly said.
All that we have mentioned has made it easy for us to provoke and bait this administration. All that we have to do is to send two mujahidin to the furthest point east to raise a piece of cloth on which is written al-Qaida, in order to make the generals race there to cause America to suffer human, economic, and political losses without their achieving for it anything of note other than some benefits for their private companies.
Don't fall into this trap again.
