We've been speculating all along, haven't we?
If the U.S. goes down the martial law route then it won't be short and it won't be pretty. People are talking about mass arrests, shipping people to Gitmo, executions, and the like. How do yo back off from that? People seem to think that we can declare martial law for a month or two, hold a new election, then go back to normal. But 'normal' means the Supreme Court striking down your election as unconstitutional and your arrests as illegal while Congress immediately impeaches and removes the president. So I don't see how martial law doesn't run for a long time.
We're running thru a military operation script. It's phased. What we may believe today, will have to be updated tomorrow.
With that said, the number that I hear... and *makes sense to me* is 3 months. But, that number can change certainly once we see what last gasps the left has.
