What was the major problem for germany at outsets of war?

The major problem for Germany at the outset of World War II was a shortage of natural resources, especially oil and rubber. Germany was largely dependent on imports of these critical materials, and the Allies had blockaded Germany's access to them. This meant that Germany had to either find new sources of supply or develop synthetic alternatives.

Additionally, Germany had a limited industrial base compared to the Allied powers, making it difficult to produce enough weapons and supplies for its military. Germany also faced challenges in its military leadership, with Adolf Hitler making many strategic mistakes that would ultimately lead to Germany's defeat in the war.
