Frankly, I'm not comfortable with ANY of it. We never should have been in Iraq, Afghanistan, Libya or Pakistan. As to the CIA and our "Special Ops" folks I think using them judiciously is OK. This IMO should have been a covert mission where essentially OBL "Woke up Dead" and we say "Wasn't us, must have been his own people"
IMO, If we had kept the mission as secret as possible we would have instilled a level of fear throughout the terrorist network that we will find you and kill you and there isn't a thing you can do about it. But instead Obama goes public in an attempt to boost his reelection effort thereby losing the fear factor that could have been used effectively in combating terror.
I think Obama's next move should be the publication of a top ten "Wanted List" along with a public pronouncement that they can surrender or meet the same fate as OBL. We have a victory of sorts and it's time we exploit our opportunity big time. I will NEVER be totally comfortable with waterboarding, I've resigned myself to that. I am however perfectly content to allow the CIA to do what they do in the way of clandestine activities. Like killing OBL. As long as it's not a duly elected head of state or government official I think it's a tool that we need and a tool that we should use when needed.
If you recall the Libertarian view that the military's prime mission is to defend the shores from invasion then one can easily make the argument for attacking OBL. What is much more of a stretch are the above mentioned incursions.
