It doesn't much matter
if it's true or not. And the air gap is irrelevant. If the Israelis have it (and they have pretty much everything save the launch codes, which they don't care about as they's got their own), then the Russian have it, which means the Chinese have it, or soon will. And if it's important, then the Israelis have it. At least when the Mob on the Hill finally decamp to their hideouts in Paraguy and places, we'll be able to shop around for the best deal on their bank account numbers to get the loot back. Or maybe it'll just be simpler to print up some more, preferably of the Treasury variety.
And to think. The Chinese actually discovered the *east* coast of America about 70 years before Columbus. Their Emperor was so impressed he let the fleet rot (remind you of anyone?). How different things might have been if they'd stayed.
We might have had Ninja Mutant Turtles, Bruce Lee movies and takeaway dinners about 300 years earlier. Instead we have The End of History (on a permanent basis).
