to me it shows an eagerness to kill instead of only a willingness to defend. if a leader of a country (or soldier) makes the choice to go to war because his countrymen are in grave danger, then that is acceptable. if however people are sent off to war because they like to see their declared enemies be bombed, shot, killed and disabled then that is morbid. obviously there are people who enjoy destroying things and killing people and there is a much higher percentage of these people in the army then anywhere else in society except maybe prisons (depending on the unit and prison) and these are the people that represent us in terrorist breeding grounds like iraq.What is wrong with that mentality? The pilot obviously thought he was shooting at an enemy convoy.
there will be international terrorists who will have developed in iraq, i believe this is inevitable. when they attack, we could say they are simply jealous of a higher standard of living, or they have a murderous phobia of democracy. instead, i think it could be they are trying to get revenge from a people (westerners) who enjoyed seeing their countrymen being bombed/shot/killed.
