Four potential problems that could undermine the United States are: 1) continued globalization without limits that misunderstands the concept of free trade, 2) a two-party political system that results in a winner-take-all approach where ideas cannot be discussed and voter turnout is low, 3) immigration issues including a lack of understanding of American culture and disputes from different religious backgrounds, and 4) uncertainty around what President Obama's policies of restarting Middle East peace talks, addressing Iran and North Korea, and resetting relations with Russia will actually achieve.
