“Crazy” is an imprecise term, but former President Donald Trump obviously does not share the reality most people live in. His mental illness comes in the form of sociopathy, malignant narcissism, and cruelty to the point of sadism. I applaud my classmate Gen. Mark Milley ’80 for taking proactive steps to prevent Trump from starting a war or further damaging American democracy. Thank you, General Milley. The American people owe you a debt of gratitude.
