Trump's threat to use the military to quell enemy within

I don't know whether Donald Trump's threat to use the military to bash his opponents in the US is just rhetorical garbage but if he becomes president again it seems pretty likely he will not brook any criticism. This is why Joe Biden and Kamala Harris have been warning of an end to democracy in the US if Trump returns to the White House. In several interviews he has called his critics scum and evil people and has, among others, Nancy Pelosi in mind, a woman who has given her working life to public service. Normally the enemy within refers to domestically-grown terrorists or anarchists but Trump is thinking only of his political opponents, especially those who want him in jail, and he has ventured to suggest that if necessary he would call in the National Guard or the regular army to keep his opponents in check. It's worth reminding everyone that this is the United States of America he is talking about where the president, while powerful, still has to adhere to the law and the constitution and to uphold democratic and moral values. It's safe to say, I hope, that if Trump does become president again, if he tries to order military chiefs to sweep the streets of his critics, they will refuse to obey their commander-in-chief. Whoever is appointed chairman of the US Joint Chiefs of Staff under a new Trump regime is going to have a tough time. But the time I have spent with the US military and with their top generals and admirals convinces me that none of them would agree to do anything against the law or the constitution within the territory of the United States. So, threaten away, Mr Trump, but don't expect your orders to be obeyed.
