officials have been really clear they are ready to impose stops on russia. they will be big, high impact. more severe than what russia has seen before and able to impact everyday life. one thing that we haven't heard from u.s. officials yet is official attribution, aka, who is behind the latest cyber attack. jake sullivan, he said yesterday that he wouldn't be surprised if russia was behind it as it is part of their playbook, but he wouldn't go any further than that when talking about sanctions for the specific cyber attack. he wanted to wait for attribution. one thing he said is a metric of success is whether the u.s. ends up in a better strategic position and russia ends up in a worse strategic position.
