It’s a lot more complex than you may realize. We have a transparency solution known as Certificate Transparency. For a “verisign” issued cert to be trusted in the browser, there must be an append only record of the cert stored in a blockchain. If Russia overrides a local trusted root, all bets are off an CTlog is not used. You can trust the CA because malicious issuance is a death sentence. And we have logs for all eternity.
