There’s loads more we can do but the Russian government might just collapse if they go too far attacking western assets. They know there will be a response “at a time and place of our choosing” and cutting the Internet properly will be extremely expensive for Russia, they will have no banking system at all and we will give Ukraine weapons to attack their oil infrastructure.
That we still have oligarchs and bratva members walking around on NATO soil in the open this far into things is insane.
