Help with Hiroshima bombing.?

You can read up on Joseph Stalin and his plans, and then write about it. Read the book "A Failed Empire" by Vladislav Zubok. The thesis can be "The bombing of Hiroshima and Nagasaki was designed not solely to force Japan to surrender, but to quell the spread of Communism throughout Europe. This is evidenced by the fact that Stalin had drawn up plans to take West Berlin, and march his troops to the English channel prior to the bombings."
