Answer and Explanation:
Although the USA is an economic and military power, it is impossible to guarantee total security in the country, which makes the USA the target of dangerous threats that can happen at any time, even with all the control and security established. Among these threats, we can cite terrorism as the greatest of it. Terrorism is not always caused by foreign and enemy nations of the United States, but also by Americans involved with incorrect institutions and ideas. Among the other threats, it is possible to avoid political intolerance, economic crises, cyber crimes, and attacks on public security, among others.
Economic threats can be brought about by the US domestic market as well as by the foreign market, since globalization allows a country's economic crisis to involve many others.
