Answer with Explanation:
The "American Revolution" was primarily caused by the<em> American's opposition against the British rule. </em>The British people were causing factions among the colonists. They also imposed "unpopular taxes," such as the direct tax that they implemented over the British colonies in America. Besides this, armed rebellion became the only solution for the colonists. The colonists believed that they were being denied by their own rights.
Because of this, the American people revolted in order to gain independence (the US War of Independence) and become a sovereign nation. This was made through the<em> United State's Declaration of Independence</em> in which the Americans stated the moral standard that they should be striving for. This then, became<u> the start of creating a national identity for the US</u>.
This kind of new system and atmosphere made them differentiate themselves from the rest thus, resulting into a more unique identity.

During Bush's second term, the great recession hit, making the American economy very unstable. The unsteadiness of the economy stopped foreign investors from investing in American stock because they were uncertain if they would make their money back. For that reason, the international support of the United States dropped.
