Yemen is a hotbed for terrorists! Luckily, I have a plan. It may not be the best, but looking at Iraq and Afghanistan, it can't be any worse: My plan is to encircle the country along the northern borders, with the support of the Yemeni government. Don't shoot ANYONE unless you have PROOF that they are highly hostile, and let anyone in who you aren't forced to arrest. (Of course, letting them out will require a bit more... scrutiny.) Then, without breaking the line, simply move the army inward, checking people as you go. Once you reach the southern point, you're done. It's over, go home, NO exception. Two potential problems: Manpower to cover Yemen's entire border will be a stretch. The only real positive point is that as you progress, less manpower will be needed, for obvious reasons. Also, it's probable that the people of Yemen as well as the countries of Yemen, Oman, and Saudi Arabia could... disagree to this response. However, looking at Iraq and Afghanistan, this can't be worse diplomacy-wise. Please give this idea serious thought, rather than dismissing it out of hand.
