Holding the line means being "comfortable with being uncomfortable". We have to endure being stripped of all kinds of civil liberties, kept in a "holding pattern" for our own safety, and repress our natural urge to fight in the ways that are unhelpful. It's like having to be a farmer when you want to be a soldier, because you're planing your future harvest in a war zone.
Psychological war is real war. Never let anyone tell you otherwise.
It certainly is real war. What would we do without our favorite wordsmith who so eloquently describes what we all are feeling and observing? Love you Patriot.
