The attack o pearl harbor was a military surprise attack that would leave us Americans, extremely ticked off at the japs and made us think' oh, these jerks tried to take out or navy, just cause they wanted to take over the Pacific Ocean. We should probably jump into the war to help the good guys!'
duh. that was probably the smart decision. And it was to, because if we didn't, more Jews and probably more people of all ethnicity would have been massacred on an even greater scale then if we did join. Also, if we didn't join this cause, the united Kingdom would probably be a smoking crater, due to the massive amounts of explosives dropped onto it's population! Don't worry, those who obsess over hating Nazis and Germans, cause i will talk about them later. The point is, if we didn't join, no, if the Japanese never bombed us, we would have never joined the war, if we never joined the war probably more than half of the worlds population would have been eliminated from existent. some of your minds just got blown. Ha, bad pun.
