Why do you trust the military or FEMA to do anything?

Is there any indication that these entities actually care what the constitution dictates after an illegitimate president has taken hold of the government?

This is not some doomer post, this is a genuine question. Where is the proof or any kind of rumor with information backing it that would hint at these entities actually holding their oath to heart?

Don't mistake this as me questioning specific individuals within the military, I'm sure plenty of individual soldiers would die defending our constitution and its principals but individuals aren't in control.
