I seem to remember that in 1979 we had a handful of Marines stationed at our embassy in Iran. Hmmm? Let see a handful of Marines against an entire country swarming over the walls. Yes, I guess they could have handled it but, the blood shed would have been terrible. The rest of the hostages were civilians who actually behaved quite well considering. Our personnel were held for 444 days and never gave in, but then the Iranians didn't steal their Ipods did they? As for the Pueblo, take a look at the group photo released by the North Koreans. They were using hand gestures to send messages. When the Koreans figured out what they were doing the hostages were severely beaten.
I have never made disparaging remarks about your 15 as I think I was not in their situation and don't know myself how I would behave, but I am not going to sit by and allow you to belittle the obvious courage of my countrymen or compare the two incidents.
