The explosion wiped out 90 percent of the city and immediately killed 80,000 people; tens of thousands more would later die of radiation exposure.
Although the war began with Nazi Germany's attack on Poland in September 1939, the United States did not enter the war until after the Japanese bombed the American fleet in Pearl Harbor, Hawaii, on December 7, 1941<span>.</span>

Patents and copyrights encourage innovation because they allow people to be rewarded for their creations. For example, if an individual creates a new type of cell phone they can receive a patent or copyright on that phone. This means the ability to make and sell this phone belongs solely to the individual or the company they represent.
Now if this cell phone becomes wildly popular and people start to buy it, it allows the creator to make a significant amount of money of their creation. Along with this, the person can sue any person who tries to take their design and sell the phone themselves.
Ultimately, patents and copyrights protect people who come up with amazing innovations and allows them to accumulate massive amounts of wealth.
