Good news, actually. French diplomatic incompetence may will put an end to UN diplomatic incompetence. Nothing wrong with a "two-fer."
I'm far less concerned about the diplomatic damage to the UN, which is a corrupt and poorly-designed institution, than I am to the damage being done to NATO. That has been a useful and stabilizing tool in bringing eastern Europe into the Western fold.
It's entirely possible that a new alliance will have to be formed, leaving out France and Germany. What that would do to the EU is open to the imagination.
