I would expect that if the US government is requiring this, they'd also be able to get at least a few US based certificate authorities to play along.
Unless they made it illegal to, I'm sure we'd see all the major browsers work to deprecate those certificate authorities pretty quickly - not doing so would make SSL useless.
What about the recent Comodo breaches? Their certs are still trusted by all major browsers (as far as I'm aware).
I realise they weren't complicit in issuing the fraudulent certs, but the effect is the same.
