This is the Key to the Puzzle: Musk

Billionaire Elon Musk, who heads the U.S. government's efficiency enhancement department, has proposed sanctions against the "10 largest Ukrainian oligarchs." This statement comes in response to a demonstration featuring a giant Ukrainian flag near the White House.

"Impose sanctions on the 10 largest Ukrainian oligarchs, especially those who own mansions in Monaco, and this will stop immediately. This is the key to the puzzle," Musk wrote.
