By the way, are you aware that Churchill was prepared to use mustard gas on the Germans should they invade England? The gas masks that the British authorities passed out to the general population in 1940 was not to protect the civilians from German gas, but British. Was Churchill "uncivilized"? I think not. Quite the contrary, he knew that the civilized must become as savage as their enemy in order to survive and in surviving, return to being civilized. Such was the genius of leaders like Churchill.
Would Churchill have bombed Hiroshima and Nagasaki? I think not, he would have bombed Tokyo and Moscow and he would have been right.
Whereas the bombing of Hamburg and Dresden --- city block by city block --- is a different situation altogether.
