War in Iraq?

Bush Snr refused to invade Iraq, Bush Jnr invaded saying biological weapons, but nothing was found. today thousand innocent Iraqi men women and children are dying.Hitlor killed 6M innocent jews,Osama killed 3000 innocent americans and asian and middle east terrorist are killing hundreds of innocent people.So what is the difference between Bush and the terrorists?This war is only making Iran & Syria stronger and USA weaker.(Bible prophecy?)Can some one give a prudent reply?
