The case was not made.
You wish to circumscribe the President's war powers, and that is not your duty.
Where in the Constitution does it say the President of the united States can have his own personal drone assassination program where he can nominate, approve, and give the order to have someone assassinated?
Again, do you accept / acknowledge the contradictory message / acts of declaring terrorists should have their day in court while simultaneously releasing some out-right while assassinating others?! It's like a 'multi-personality' approach instead of a consistent approach.
One either believes that terrorists on the battle field ARE terrorists and should be treated like one or they are 'belligerents' who should be brought to justice. Obama cherry-picks what he wants to do when he wants to do it. There is no consistent strategy ... except for what he wants to do at the time.
