Donald Trump is an authoritarian and an autocrat. For him and others of such ilk, violence is political currency in the form of raw power. Autocrats and authoritarians such as Trump are de facto crime bosses who just happen to be leaders of their respective countries.
As such, Donald Trump uses violence in an effort to intimidate his enemies and control the public. Trump also uses violence to control his allies, servants and other supporters.

WASHINGTON — When President Trump signed a $716 billion military spending bill on Monday, he claimed the authority to override dozens of provisions that he deemed improper constraints on his executive powers.
In a signing statement that the White House quietly issued after 9 p.m. on Monday — about six hours after Mr. Trump signed the bill in a televised ceremony at Fort Drum in New York — Mr. Trump deemed about 50 of its statutes to be unconstitutional intrusions on his presidential powers, meaning that the executive branch need not enforce or obey them as written.
Among them was a ban on spending military funds on “any activity that recognizes the sovereignty of the Russian Federation over Crimea,” the Ukrainian region annexed by Moscow in 2014 in an incursion considered illegal by the United States. He said he would treat the provision and similar ones as “consistent with the president’s exclusive constitutional authorities as commander in chief and as the sole representative of the nation in foreign affairs.”
