Put the following events in the correct sequence: Doolittle raided Japan, Atomic bomb dropped on Hiroshima, Soviets declared war on Japan, Japan bombed Pearl Harbor.

The correct sequence of events reflects the chronological order of significant actions taken during World War II that involved Japan and the United States.

Starting with Japan bombing Pearl Harbor, this attack occurred on December 7, 1941, and was a pivotal moment that led the United States to formally enter the war against Japan. Following this, Doolittle's raid on Japan took place on April 18, 1942, serving as a retaliatory strike that boosted American morale despite its limited military impact.

The next significant event was the Soviet Union declaring war on Japan, which happened on August 8, 1945, just days before the atomic bomb was dropped on Hiroshima on August 6, 1945. The atomic bombs were crucial in bringing about Japan's surrender, effectively shortening the war.

Putting these events in sequence, we have:

1. Japan bombed Pearl Harbor

2. Doolittle raided Japan

3. Soviets declared war on Japan

4. Atomic bomb dropped on Hiroshima

This sequence is consistent with the historical timeline, making the correct answer the one that accurately reflects these events in order.
