Well he’s “taking out” generals almost weekly.
This is probably why he’s doing that.
Rumblings have probably bubbled up to the president to the tune of “don’t try it”.
AFAIK most military mutinies that toppled sitting dictators were not staged by generals but colonels from meticulous planning to actual staging it, they'd asked their upper class friend already generals co alma matter military academy in the middle of coup if they want to join in the mutiny, most chicken P-C senior officers would wait until almost to the end who they'd side with. Esprit de corps will minimize or avoid killings among themselves. Bunch of colonels had ended Ferdinand Marcos regime, Col. Muammar Gaddafi never promoted himself to general.
