You're describing problems, in fact the exact same problems that you'd have with an entirely domestic source as well. I'm asking about how it would be stronger, or better than a purely domestic source. The EU absolutely should have it's own cloud infra. Couldn't agree more. How does an exclusively domestic IT infra benefit the EU, is the question. If they had their own, and were also able to source from the US, from Japan, Korea, Taiwan, [insert other allies] they'd be faster at adapting to a change in supply.

Russia is a bad example, they're doing stupid shit, the same as the US. Hurting itself in it's confusion. But I guess it's a fair point, if you're willing to cut off your own feet, you don't need to depend on importing shoes. And it might make sense to build exclusively domestic leg stub sock factories, given the rest of the globe doesn't want to cut off it's own feet.

I wouldn't actually suggest that as something the us should strive to emulate.
