The best advice is to wait? May be. I don’t know how long it would be best to wait, though. No one can see absolutely everything on the area of operations of the future.
Granted, though, Democrats and other “progressives” tend to let things get way out of hand before turning the U.S. into a real monster of a war machine in a late fight for survival.
Many people also assume that a few nukes lobbed here and there will be the end of such a conflict. It would only be the beginning of a conflict that would probably be larger than nearly all people could imagine. Essentially everyone would be drafted, and likely for a very long time.
The U.S. will never have a military draft again.
