What if, instead of invading Czechia in March 1939, Hitler would have invaded and occupied the Baltic countries instead?
FTR, Hitler's logic behind this move would be that Germany needs more Lebensraum and that the Baltic countries are the easiest place for Germany to get Lebensraum in the near term.
How would Britain, France, Italy, the Soviet Union, Poland, Romania, the United States of America, and other countries react to such a move by Nazi Germany in March 1939?
