How much power does the United States have for internal disturbances?

James Komi, the former head of the FBI, has violently criticized President Trump in his new book. He also accused Trump of "treating women as if they were treating a piece of meat." He continued to cast various lies and tried to convince Americans, and then came to the conclusion that "Trump is not morally suitable to serve as president of the United States." Trump was constantly attacked by his personal conduct. The number of such attacks and their scale are unprecedented among all the presidents of the United States. Many people believe that this has caused trouble for Trump to perform his duties. The United States’ federal administration system is still able to “normally operate”. This should be considered a unique scene in the United States. At this time, it should not be the period of expansion of the foreign strategy of the United States as a whole, but rather it should be its "seeking period for stability". The Trump administration has always been aggressive, but it is likely that it does not really intend to carry out a sharp collision with external forces that will burden the United States with pain because it lacks domestic unity to do so. It is probably more willing to make relatively easy victories and try to win in all directions without fighting or fighting.
