No, no, no, no, no.
Planning a murder and committing a murder are not the same thing, and the government can't kill a person (without first obtaining a conviction) simply because he is planning one or more murders. How certain the government is that such planning is going on makes no difference to the rights of the accused.
Plotting murders in service of and under the protection of a hostile power in a region that will not allow the US to use military force to recover or eliminate him. Its not a nice, clean situation. Should we just ignore the nation then and send troops to get him, risking sparking an even messier conflict? Should we just ignore the situation entirely and wait for the actual terrorist attack?
I'm arguing this based on the assumption that the current information is accurate, something I recognize has quite a bit of uncertainty to it, because I want to know what, if we knew with 100% certainty that he was plotting something deadly and feasible, what course of action you think we should take.
