Germany had to fight britain alone
This just refers to the fact that at the time of the Battle of Britain, all other European countries had been overrun by Nazi Germany. The USA was still neutral so Britain was standing alone against a formidable enemy.
By 1940, German forces had overrun most of Europe except for Britain. No other country was prepared to become involved in what was seen as a European war. Therefore Britain stood alone against the very powerful German forces and spent the time re-arming and retraining its armed forces. Nothing much happened until December 1941 when Germany declared war on the USA and they entered the war. Britain was no longer alone.

The USA did not enter the war until after Pearl harbour in December 1941.
