Including the US right? And I don't mean in a conspiratorial sense. Just in the sense that they wouldn't deny it because it's their home country (Say Windows certs or Google certs), and at the very least they can issue warrants, gag orders, or triple letter agency bypasses.

Now it only sounds weird when a country exherts their national sovereignity because the US doesn't need to perform any additional steps to install any of their Certs, they have hundreds of them by design.
