• Vanity and spite. After all, he’s not emotionally mature.

• With some probability, he’s seeking attention from his supporters and needs to satisfy lobbyists who bought and propagandized his way to power. He has to deliver them goods. This is how he shows that he intends to deliver the goods… that he actually cannot deliver without changing the constitutional order very much.

• Maybe he wants to test the mettle of the terrible Renewable Industries Complex - an industry very prone to organizing coups and hiring assassins. If I were him, I’d consider twice, all the people in the solar business that I know have been extremely menacing. ;P ;P ;P
