>There is going to be a lot of debate over whether this specific operation was legal

Or maybe there wouldn't be any debate and people will move on to the next bombastic thing he does. Populists get away with everything by simply not engaging, people get tired and seek new entertainment and there's no actual checks and balances beyond the decency. When someone has no claim of decency, they are untouchable. No one will ever arrest them, stop them or deny them anything because they can just replace those who do not obey. Maduro, Trump, Putin, Erdogan, Orban and many others are made from the same cloth.
