Boy, you haven't shown very sharp critical thinking skills. An aggressor can't be equated to a victim, and the military operations of an aggressor are not the same as when a victim is defending itself. Britain invaded Iceland in 1940. Britain also invaded Iraq in May 1941 to counter a pro-Nazi coup. These were legitimate forms of self-defense, were justified.

Britain and Russia invaded Iran in August 1941 because the Iranian leadership was pro-Nazi. Russia also invaded Japanese-occupied China in August 1945 because she was obligated to do so by the terms of the agreements at Yalta.

For you to condemn the Allies for "attacking other countries" reeks of 1940s German or Japanese propaganda.
