What the allies did in WW2 was perfectly moral. The reason we won World War 2. We fought more brutally than they did. We bombed the Germans and Japanese into submission. You don't win wars by being less nasty than your enemy. IslamiNazis won't be defeated by showing them peace signs and handing them flowers.
You win by doing what we are doing. Actual ordnance laid onto military and terrorist installations; deposing of leaders; manhunts of the enemy leaders; killing of the enemy; and keeping the moral "high ground" in the propaganda aspect of the war.
Never THREATEN...state your POLICY....act if it is not heeded.
