The solution is to connect them with HVDC, right? That might not be a great solution for making a single national-grid, but it would allow the 3 grids to mutually borrow from each other, right?

Anything you can find to support grid interconnects as black-start capacity?
From what I understand there can be a number of different techniques for black starting a grid, including pumped storage / hydro generation because they can be started with very modest power. Being able to jumpstart a grid based off of a neighbouring grid seems to make sense.

This might counter the grandparent poster if Asia was on the same synchronous grid, but it's not.
Here's the map including all larger powerlines
It spans 8 timezones.
Europe is just larger in capacity, not breadth.
I've also heard, but I can't explain so you'll have to look it up yourself, that none of this matters when keeping a grid in sync anyway. It just works out.
