Roosevelt was playing footsy with everyone from Stalin and Mao to the Vichy French and Italian ex-fascists to South American dictators and the Saudis, all in the name of winning the war.
If hosting some Muslim leaders and keeping them from throwing in with the jihadis would help our war effort he would have done it.
I remember one outstanding statement from Roosevelt. Would you lie for good reason? Absolutely.
Churchill: “If Hitler invaded Hell, I would at least make a favorable reference to the devil in Commons.”
