I'm sure if Hitler could help him land on Mars, Elon would make a deal with him. Remember Trump and Elon had a falling out over DOGE. Not sure what there relationship is now.
By wasted trillions you mean shit like the us having the most expensive military ever and losing to a country that kills lesbians after commiting a war crime on Iran.
