This is a hard question that is open to discussion even among historians who specifically study World War 2 as a topic and specialize in it.
The most frequent answers that would probably be given is:
1. Pearl Harbor - with the attack of the Japanese on Pearl Harbor, USA was effectively dragged into the war which may have tipped the odds in favour of the Allies.
2. Stalingrad - the Soviet Union captured a huge German army in Stalingrad. The soldiers from this army were either imprisoned until the rest of the war or died due to hunger. In effect this meant that the German forces lost a whole army on the Eastern front.
3. Normandy landings - the Normandy invasion gave the Allies a foothold on the beaches of Western Europe from where they could invade through the mainland right into Berlin by the end.
Spanish Florida (Spanish: La Florida) was the first major European land claim and attempted settlement in North America during the European Age of Discovery. La Florida formed part of the Captaincy General of Cuba, the Viceroyalty of New Spain, and the Spanish Empire during Spanish colonization of the Americas.
Acquisition of Florida: Treaty of Adams-Onis (1819) and Transcontinental Treaty (1821) The colonies of East Florida and West Florida remained loyal to the British during the war for American independence, but by the Treaty of Paris in 1783 they returned to Spanish control.
The Soviet Union suffered the most casualties. They lost around 24 million people to the war.

On June 20, 1790, Secretary of State Thomas Jefferson Secretary of Treasury Alexander Hamilton and Representative from Virginia James Madison met to discuss issues at Congress. These men were political opponents.Hamilton, a Federalist, wanted the Federal Government control the political and economic power; Madison and Jefferson, Republicans, wanted the states to have this power. This meeting is known as the “Compromise of 1790.”
During this compromise It was agreed that the capital would be moved to the South. In this way the south received compensation over the war debts between Hamilton and Jefferson. The result was that Philadelphia was replaced by Washington as the nation´s capital.
