War
What is it good for? Absolutely nothing (for average folks, though it does create myriad possibilities for elite profiteering). This is why a good leader is very cautious about putting our young men & women into harm's way. Doing this to distract us from probes into Russian attacks on our electoral system and administrative incompetence is nearly always a horrible idea, reflecting either cold-hearted disregard for average folks or inexperience, or both.

Experience matters. Growing up as a rich kid who inherits great wealth and does nearly nothing of value with it does not constitute relevant experience, nor does being the son-in-law of that rich kid.

Success in world politics is already challenging enough. We are asking for unnecessary trouble with a leadership style that is so profoundly disconnected from the realities of regular folks and even from the realities of what it takes to be a successful business leader. And unaware of its own incompetence.
