EGO. That's the answer for EVERYTHING regarding Donald Trump. He's in this presidency because of his ego. He wants the wall because of his ego. He wants a bloated military, military parade and partnerships with tyrants (Kim, Putin, etc) because of his EGO.
The man lives and breathes by the almighty EGO. He is a veritable SLAVE to it and he can never be free of it. He cares for nothing and no one but himself. His own narcissism and neverending quest for "legend" status won't allow him to see/care about anyone else.
That's why everything has to be "big" and "beautiful" to him. It's why everything has to be "the best" and "the strongest" and "the richest", etc.
Nothing else makes sense.
The man isn't even a unique egotist--he's a cliched one. I wouldn't be surprised if the guy had a gold-plated toilet seat in one of his homes. I'll bet that's why he dies his hair and skin yellow/orange--he's trying to make himself look like a gold nugget.

He blew his chance when he turned down the DACA-conditioned offer.
"Art of the Deal", my a$$. He's a fcking orange buffoon.
