f Russia won't listen to Ukraine, and not, e.g., invade Georgia or other neighboring countries, then Ukraine is under no obligation to listen to Russia.

If you are at a crosswalk with a "stop for pedestrians" sign, and a truck is bearing down at 50 mph in a 25 mph zone, you have every right to step off the curb.

If you are in lower NY bay in your sailboat on the starboard tack, and your course takes you in front of the Queen Mary II, you have every right not to yield.

Excellent point...The unwritten, but nevertheless always worthy of consieration, law of gross tonnage often applies outside of maritime encounters.

Russia has amply demonstrated that it is not the Queen Mary II.

More like: The Moskva.

And Ukraine has sufficiently demonstrated that it is not a mere "sailboat," but rather a formidable adversary.
