Streisand probably doesn't know about the Rape of Nanking, the Bataan death march, the death ships, the mass murders of prisoners and civilians, the beheadings, the starvations, the diabolical medical experiments, and the refusal of the Imperial Japanese military to surrender. Nitwits like Barbra Streisand, who cry about Hiroshima and Nagasaki, never mention those.
She probably considers the Doolitte Raid to have been a terrorist act. Then again she probably never even heard of Jimmy Doolittle.
