A foreign gov getting all your security researchers and staff's personal info with their family and tax and medical records doesn't sound great.

That's just from the top of my head. Exploiting such a trove of data doesn't sound complicated.

Yeah that ignores about two thirds of my point, including that it would never get to the "Exploiting such a trove of data doesn't sound complicated" stage with a higher probability than storing it within one's own territory

I'm in agreement with your second point, I think moving data in the country isn't trivial either and requires a pretty strong system. I just don't have much to say on that side, so didn't comment on it.
