Why did the situation look bad for the Allies in the early 1940?

In the early 1940s, the situation looked dire for the Allies due to a series of rapid and significant victories by Axis powers. Germany had successfully invaded and occupied much of Western Europe, including France, while Italy expanded its influence in the Mediterranean. Additionally, Britain faced the threat of invasion and was enduring extensive bombing campaigns during the Blitz. The United States had not yet entered the war, leaving the Allies reliant on limited resources and support.
