"Why did America wait until Pearl Harbor to join the war?":

Before Pearl Harbor, the U.S. had strong isolationist sentiment from its population and government, rooted in avoiding the entanglements of European conflicts after World War I. Additionally, the U.S. was profiting from trade with both Allied and Axis powers, and there was no direct attack on U.S. territory or interests to galvanize public support for entering the war. The surprise attack on Pearl Harbor eliminated isolationist opposition and gave the government a clear, justifiable reason to declare war.

"At which point did the Allied Powers gain the upper hand, and why?":

The Allies gained the upper hand in 1942, with the combined outcomes of the Battle of Stalingrad (Soviet Union repelling Germany's eastern advance, inflicting massive Axis casualties), the Battle of Midway (U.S. destroyed Japan's core carrier fleet, ending Japanese naval dominance in the Pacific), and the Allied invasion of North Africa. These events halted Axis expansion, put Axis forces on the defensive, and allowed the Allies to begin coordinated counteroffensives across all major theaters of war.

Why did America wait until Pearl Harbor to join the war?

The U.S. had widespread isolationist sentiment, seeking to avoid repeating World War I's European entanglements. It also profited from neutral trade with both sides, and there was no direct attack on U.S. interests to unify public support for war. The Pearl Harbor attack ended isolationist opposition and provided a clear, justifiable cause to declare war.

At which point did the Allied Powers gain the upper hand, and why?

The Allies gained the upper hand in 1942. Key victories at the Battle of Stalingrad (halted Germany's eastern advance, caused massive Axis losses), the Battle of Midway (destroyed Japan's critical carrier fleet, ended its Pacific naval dominance), and the North African invasion halted all Axis expansion, forced Axis forces into retreat, and allowed the Allies to launch coordinated counteroffensives across all war theaters.
