Like most Americans I never felt Air Strikes would do very much even massive B-52 strikes won't do much unless they bomb city centers like Bagdad and Bagdad is not the enemy , Ground Troops would come as close to a win if there is one than anything else , that of course has been tried no win , not from lack of trying just not enough troops , how many troops would be enough and what would be their goal , I would start with a million then take a look at it , their goal that's a question that needs addressing I don't know the answer to that . .
