Nazi Germany launches its war against the USSR. As such, FDR hopes Germany’s attention will slacken on the Atlantic. Yet, if Soviet Russia collapses, then Japan would be free to attack Siberia or Western held territory in Asia. FDR must decide it now is the time to move forcefully against Hitler. Meanwhile Churchill and FDR learn of the slaughter of the Jews in Poland.
Soviet Gen. Kirponos does reasonably well in defending his SW Front, when he is told what is going on. But that is irregular at best. Soon, Lvov falls and all know that the next major battle will take place along the Stalin Line.
