Wasn't that the intel estimate on how long it'd take Russia to take over? I saw Biden's statement that he was sending thoughts & prayers while he watched this and would talk it over with world leaders tomorrow. Since the last few rounds of sanctions did nothing after Crimea, I don't see this changing things.
By the time there is a real response, it's looking like this may be over. Given that their urgency was "I'll talk to world leaders about what to do tomorrow" rather than "let's enact the plan we already prepared during the weeks of warnings" I think we know which way things are headed.

Given that it's apparently not urgent enough to do anything but watch this on TV until morning, it doesn't look like a priority to me.
