Hubby, I don't understand...After September 11 , the US went to Afganistan but the bombings in Bali and in many other countries happened the same; then, the US went to Irak but the bombing in Madrid, and now in London went ahead the same; so, apart from killing many thousand Iraqui and almost two thousand American, can you please explain to me what the US have achieved in preventing acts of terrorism, with those two wars?
