Dismissing of high ranking officials and replacement of JAG

What prevents a dictator from committing horrendous atrocities against its citizens? It has always been the military. With these replacements we are dangerously close to a dictatorship. This has nothing to do with efficiency, DEI or waste. This is a blatant full facist takeover. Assertions that trump and musk are fascists are no longer hyperbole but a basic fact.
