<s>[INST] Can you tell me about ww2 [/INST] World War II (WW2) was a global war that lasted from 1939 to 1945. It was the deadliest conflict in human history, with an estimated 50 million to 85 million fatalities. The war involved most of the world's nations, including all of the great powers, and was characterized by the widespread use of new military technologies, such as aircraft and tanks, and the involvement of civilian populations.

The war began with the invasion of Poland by Germany in September 1939, which prompted the United Kingdom and France to declare war on Germany. The war soon spread across Europe, with Germany conquering much of the continent and establishing a series of puppet governments. In 1941, Germany invaded the Soviet Union, triggering a massive and brutal conflict on the Eastern Front.

Meanwhile, in the Pacific, Japan, which had been expanding its empire throughout Asia, launched a surprise attack on the US naval base at Pearl Harbor in December 1941, drawing the United States into the war. The war in the Pacific would ultimately end with the atomic bombing of Hiroshima and Nagasaki by the US in August 1945.

The war had a profound impact on the world, leading to the formation of the United Nations and the beginning of the Cold War. It also resulted in the deaths of millions of people and the displacement of millions more, with devastating consequences for both the victors and the defeated. </s><s>[INST] Can you tell me about the winners of World War II [Provide a bulleted list of the victorious countries of World War II with a short explanation of what they did during World War II].
