Problem: Terrorists are contemplating or attempting to attack the United States. You are POTUS and a liberal who is beholden to your far-left constituency. How do you handle this problem overseas and domestically?
Overseas: Send in a double strike of Predator drones to hit a terrorist enclave in Pakistan, ensuring suspected terrorists are swept clean off the map and no longer a persistent threat to the USA.
Domestically: Arrest the underwear bomber & read him his "rights" that are normally reserved to US citizens. Ensure he is given a trial in accordance with the US Constitution because, after all, he is innocent until proven guilty and this is not an act of war, it's a matter for the civilian courts. For others, pull them out of Guantanamo Bay and transport them to the scene of the horrific crime they perpetrated on the citizens of this country where they may also receive a trial under the protections of the US Constitution.
I'm OK with the overseas answer...it gets a B.
As for the domestic policy, it's not worth a letter, just the finger.
