Thinking about the difference between Nixon's last days in office compared to Trump's I came across the following;
"White House Chief of Staff Alexander Haig also worried about suicide. A few days earlier, the despondent President and his Chief of Staff were alone when Nixon started talking about how disgraced military officers sometimes fall on their sword. To Haig, the Army General, Nixon said, “You fellows, in your business, you have a way of handling problems like this. Somebody leaves a pistol in the drawer.” Haig was stunned. Then sadly — bitterly — Nixon said, “I don’t have a pistol.”"
The difference, if Nixon did have a pistol he would have only needed one bullet. Trump would demand 78 million.
