Effective Bombing?

From my miniscule knowledge, I do believe that during a war bombs fall, and when bombs fall they explode, and when they explode, people in the neighboring area of explosion have a greater probability of death. However, just as in every case, there are exceptions to each ‘theory’. The war that rages the Middle East is quite a different from ones previous in the history of men. The art of war has changed with technology but the basic principle of one army vs. another still stands. This modern war in the Middle East proves otherwise. This war against terrorism is not between US troops and the enemy. This enemy is very complicated, ranging in all ages and genders, but most significantly no uniforms! How are US soldiers supposed to right an army that does not exists, how do people expect American soldiers to wage war against entire countries, if not regions of the world. I think it is crazy that this interview deals with talking about how bombs explode. How can we say that one building is a target, and the one less than five feet away not a target? This enemy of terrorist hide in one house to another and recruit entire towns to aid their cause. When Americans get the signal that one building is a target, they drop bombs. Yes the neighboring buildings might get destructed and the people in that area will get hurt. People may argue that these people might be innocent and they do not deserve to be hurt by these bombs. But from the prospective of American soldiers, how can they only destruct the target? These terrorist are unlimited in numbers, they have full support of their towns. I think that if a person is truly innocent, then they should pack up their home and take their family to another country where they do not have the risk of being killed by American bombs. War is a ugly thing, people die, it cannot be avoided.
