An old episode of “Madam Secretary” concerned a President whose erratic behavior necessitated his removal from office until doctors could certify him fit to resume office. The straw that caused the invoking of XXV Amendment was his threats to use nuclear weapons in Iran.
Several times President Trump has threatened the use of nuclear weapons on North Korea and Iran, but as usual, he has not carried them out. His bombastic personality means his words are now perceived as meaningless and not to be taken as more bluster when his threat could be real. Analogy is boy crying wolf.
Trump has been paranoid for many years and now has become extremely paranoid. He has fired many of his chosen secretaries and assistants who he perceived were not completely loyal to him.
He took narcissism to an extreme level when he said “These people will tell you how great I am,” and then sat to the side of the dais. The leaders of our government were then required to use “great” over and over in their loyalty speech. Sounded Hitler-like.
Trump has created a fantasy world with all the crazy ideas and conspiracies he reads on the internet or suggested on Fox by their talking heads or their guests. He often says the pandemic is a hoax causing his believers to rebel against the science.
He has been a habitual liar since he was a little kid and now he seldom every tells the truth. A great example was during an interview where he was saying we had fewer cases per thousand of Covid 19 than any other country in spite of showing a sheet indicating we are halfway down the list.
Maybe it is time to invoke the XXV Amendment!
