Trump also took a lot of the safeguards off drone strikes that were designed to avoid civilian casualties. Not that things were perfect under Obama, but not only did it get worse under Trump but the reporting/accountability measures also went away.

Honestly I dont think the president has that much to decide when it comes to military actions. What he does is announce the decisions of the military (or in other words, he is "following their recommendations"). Biden cant even remember the name of the Australian president after "being in talks" with him for weeks. His whole job seems to be reading from teleprompters (or trying to recite a speech, and stumbling).
