"All four appeared frightened."
Why are they afraid of the peace-loving radical, Islamic Fascists whom they are there to free from American occupation?
I say, let them fare for themselves. I wonder if they would object to American GIs busting in and rescuing them? Hmmmmmmmm.
I had to consult the Code Pinko Useful Idiot manual for your answer: Since the Pinkos, their fellow travelers, claim to support the troops and want them brought home NOW, my guess is they would not want any of our fine military in harm's way for such a rescue mission. They would not want them "maimed for a (peace activist)lie".
