Well - the number of Indians killed by Americans in war is zero. Number of Indians killed by Pakistanis / jehadis / foriegners from central Asia is a few millions in the last 1000 years. Numbers of Indians killed by communists and chinese is maybe in 10s of thousands. The British fought in India and maybe killed a few 1000 in wars as well as a few in cold blood like in Jalianwala. Nazis killed millions deliberately without war. Stalin and Mao another 10 million without a war. I don't know how many people Americans have killed when there has not been justified war. I have personally viewed Iraq as a justified war because it enabled Americans to establish base right in the heart of middle east and vietnam/korean wars were against spread of communism.
