Was the attack on Pearl Harbor a bad move for Japan ?

The attack on Pearl Harbor was a bad move for Japan because the united States declared war on them, they deceitfully attacked the pacific fleet and it entered the United States and Japan in to a four year long conflict. The United States declaring war on Japan broadened Japan’s front as they were already in China, Korea and various other pacific islands and countries, trying to take over that part of the world, and fighting the Americans would require men and resources elsewhere. The Japanese bombed Pearl Harbor on December 7th, 1941 in a surprise attack consisting of the Japanese fleet bringing aircraft in range to bomb the United States pacific fleet and airfields. The United States declaring war on Japan led both countries into four years of long, bloody conflicts, jumping from island to island which the Americans became the successors of and inched closer and closer to Japan. Instead of an amphibious assault on Japan, the United States dropped two atomic bombs on Hiroshima and Nagasaki to end the war in the pacific.
