If they start a draft, it's POSSIBLE that they can pull it off, simply by actively not touching anyone who is a potential revolution risk. Which is a LOT of people...
But this is like landmine soccer, they're not gonna pull it off.
You could say they're doing that now - and people would rather go hungry than die in Iran.
So they're apparently talking about making it official... But I just see no possible way they can thread this needle in one shot without touching off action.
You're gonna have draft resistors, anti-trump leftists, illegals, cartels, all suddenly on the same side...
