Explanation:

The London Blitz was a German bombing campaign on London, not directly leading to US entry. The capture of France by Germany and Axis invasion of North Africa were European/African theater events. The attack on Pearl Harbor (December 7, 1941) by Japan directly prompted the US to declare war on Japan, entering WWII.

Answer:

the attack on Pearl Harbor
