America is one of the most powerful nations in the world. If America becomes a dictatorship all of the world can be in danger. Freedom could be instinct. Though the U.S. is a Democratic Republic so not a full fledged democracy. If the U.S. fails the whole world fails.
“Patriotism means to stand by the country. It does not mean to stand by the president or any other public official, save exactly to the degree in which he himself stands by the country. It is patriotic to support him insofar as he efficiently serves the country. It is unpatriotic not to oppose him to the exact extent that by inefficiency or otherwise he fails in his duty to stand by the country. In either event, it is unpatriotic not to tell the truth, whether about the president or anyone else.”
― Theodore Roosevelt
