1. It's a MEMO making the case for a policy.
2. If you leave the U.S. and join up with al-Quaida and become a "senior operational leader", then you are an enemy of the United States.
3. I have a hard time believing any Congressman or Senator who support rendition, enhanced interrogation, or any number of Patriot Act policies would have a problem with killing an terrorist enemy of the United States before they can plan an attack.
If you're in war and you suddenly change sides and begin working with the enemy, do you have the right to scream "but I'm an American" as your former squad guns you down?
Your comments seem like the typical anti-Obama nonsense that has become too common in the last 4 years. You don't even respect the right of your country to protect you from an enemy (that happens to hold a U.S. Passport).
Re: your continental U.S. hypothetical. Think about it, if a senior operational leader of al-Quaida is in the U.S., he better be here standing trial or giving up intel. If you've completely given yourself over to religious extremism and the U.S. is your sworn enemy, then your 'citizenship' is a moot point.
