Hey Guys,
IOTL Poland gave Lithuania an ultimatum on 17 March, 1938 to establish diplomatic relations with Poland, thus causing a de facto renunciation of Lithuanian claims to the Vilnius region. The Soviets supported the Lithuanian claim, but they made it clear they wouldn't militarily support Lithuania due to their border conflicts with Japan in the east.
Hitler was looking at the Memel Territory, he said it was Germany's second-most important issue after the Sudetenland and even said to the Poles that, if a Polish-Lithuanian War broke out his troops would occupy the port. Thus he told Lithuania to concede to the Polish demands.
However, what if Hitler took a pro-Lithuanian view? Seeing the Polish ultimatum as a kind of 'Slavic Conspiracy' to weaken the Aryan claim to Central Europe, or some such nonsense.
What if Hitler had outwardly supported Lithuania and declared that if Poland were to attack Lithuania he would militarily support the Lithuanians? How would Britain and France react, IOTL they were focused on the Sudetenland, however if German focus shifted from there to Poland they'd obviously shift their focus too. Would we see the Allies demand Poland retract their ultimatum, seeing it as a Polish attempt at domination of the area? Or would they support Poland?
If war did break out would it be kept as a German-Lithuanian vs Poland War, or would we see other sides interfere? Could we see an agreement between Lithuania and Germany saying that for German support Lithuania would cede them Memel?
