This is based on what? Surveys, polls? Where there could be possible risk of retaliation if they answer a certain way?It's strange that you continue to make this claim when I already showed you that the military rank and file is in fact left leaning - why would they join the right? Did you just not internalize that data because it went against your doom narrative?
Does it matter what the rank and file or what the officers say or do? If they lose control of their units, it's over. If even 20% of the military broke off, it would be disastrous and bring about untold misery.
And right or wrong, I don't think Biden has it in him to do what you had suggested. He would hand over the Presidency, even if there were obvious shenanigans. It would arguably save a ton of lives. Sometimes you just have to know when you've lost, and we're not the first great empire to fall into darkness. This was all set in motion in the 90s, the GOP long game that is. Don't act surprised that it's now finally playing out.
