Secretary of State John Kerry has given Russia until Monday to reverse course in the Ukraine, or face "serious consequences."
Perhaps he will say "Nih!" to Vladimir Putin.
One thing is pretty obvious, though: there's not much the United States can do next Monday that will faze old Vlad. Which would seem to argue for not setting oneself and one's nation up to look foolish through silly posturing.
Mr. Obama and his administration seem to have a knack for such things. But not to worry. Perhaps we'll get a shrubbery out of the deal.
And the world holds its breath....
