Because he changed his title from Defense to War; (which isn’t really legal), he perceives he has the authority to order people killed.
It’s been asked of him multiple times to present evidence of who these people are in the boats, he’s failed to do so.

This shines a bright light on hate and disrespect for the law.
Because Trump is puppet master of the legislative/judicial branches he fears no accountability.
