Under the new government of Petro Poroshenko, Ukraine sent its forces to the southeast to crush the separatists. They failed. Rising casualties and a separatist drive on the city of Mariupol have apparently persuaded Kiev to seek a ceasefire and peace.

Needless to say, those who celebrated the overthrow of the pro-Russian regime in Kiev are now apoplectic at Kiev’s apparent defeat.

Yet, on Sept. 5, the New York Times wrote, “The Americans have no illusion that Ukraine could ever prevail in a war with Russia.”

That is realism. But if Ukraine’s cause is militarily hopeless, what would be Estonia’s chances in a clash with Moscow? Estonia has three percent of Ukraine’s population and is less than one-tenth its size. If Moscow decided to take Estonia, it could do so in 48 hours.

And should Putin engage in so rash an act, what would NATO do?

Would 28 NATO nations declare war and send troops? Would the United States declare war on Russia and conduct air strikes on Russian forces inside and outside Estonia?

Would we send aircraft carriers into the Baltic Sea? Would we start a war with Russia that could lead to early use of tactical atomic weapons, devastating Estonia and causing massive deaths?

How would NATO save Estonia without destroying Estonia?

To eliminate second thoughts about our war guarantee to Estonia, some in Washington are calling for permanent U.S. bases and the stationing of U.S. troops in the Baltic states, so that any Russian incursion would lead to U.S. causalities and a definite clash with Russia.

Presumably this threat would deter Russia in perpetuity.

But if it doesn’t deter Putin, or if a future Russian ruler regards it as a bluff and chastises Estonia, what do we do then? Put the B-2s on alert and go to DEFCON-2, as we did in the Cuban missile crisis?
