As far as the collapse of the United States is considered I would have to disagree. The United States is still considered having a global superpower and considered as the leader of the free world.
The leader of the free world:
This is not, however technically, an existential crisis. No foreign army is about to invade the United States. The Soviets are 20 years gone, and Russian ICBMs are now aimed at the open ocean. The nation isn’t in a depression. Now there’s been no run on the banks. American have been for decades now the number one global economic power.
The downgrading of U.S. debt may be more representative than empirically significant, but it gives one small data point to those who argue that America isn’t what it used to be, which means it is an empire in twilight.
America is somehow managing that decline, creating the transition to post-superpower status as smooth as possible, Through assisting Americans to understand and adjust in their new circumstances.
Obama’s thought about America:
Obama do believed in American exceptionalism. But want to improve it to a high level. He want it to place on the top as compared to Greek exceptionalism or British exceptionalism.
Right from the day, Obama has been seen more emphatic in speaking about America’s special role in the world. That is the reason in his most recent State of the Union address, we saw him speaking of the need to sustain the leadership that has made America. He do not satisfied with the current political position of the country. He want to see his America on the top of the world.
Therefore I will never agree with the opinion that United States empire, the most wealthy and having the strongest military force will come to an end. Rather it will touch to the sky limit.
