Pearl Harbor,<span> in Hawaii, the site of a major US naval base, a surprise attack happened in 1941, by the Japanese killed over 2,000 people. This brought us into WWII.
9/11</span> is when the Muslims hijacked three planes, two crashed into the Twin Towers in New York and the other crashed into the Pentagon. 9/11 were some of the deadliest attacks. Nearly 3,000 people died.
While both are tragedies caught by surprise, there are distinct differences between the two. The first is the culprit behind the tragedies. The bombing at Pearl Harbor was a surprise attack on the West Coast of the US organized by Japan. 9/11 was a surprise attack when planes flown by members of an Islamic terrorist group crashed into the twin towers and the Pentagon. Hope this helps!
