It would be good if future elected politicians would choose to remove the president power to starting wars or killing people in special military operations. I am reminded of this 13 year old rap news video being very prophetic, including mentioning bombing Iran. https://www.youtube.com/watch?v=WpMPu5p_QXU

It doesn't really matter what powers the president is "given". As seen with this current US president, there're always ways to grab more power, directly or indirectly, no matter what checks are in place. And there are certain things that a president has to be allowed in some way for them to be able to act as a president in the first place, which preempts making them fully off limits.
