However, the record will likely show that Ukraine's new leaders committed at least four immediate blunders that contributed to the situation that exists today:
1. They failed to catch Yanukovych on the way to Russia. He should have been an easy catch. Now Ukraine has to live with the specter -- however remote -- that he will return someday. Fortunately, Putin has had the good sense to keep his distance from Ukraine's former president in public, even though he shouldn't be harboring a man suspected of mass murder and mass financial corruption;
2. Disbanding the hated Berkut riot police may go down in history as a blunder akin to the United States' disbanding of security forces loyal to deposed Iraqi dictator Saddam Hussein. With that one move, Ukraine's new leaders threw out onto the street a hate-filled, violence-soaked and highly trained group of killers.
3. Recognizing reality. After victory, Ukraine's new leaders should have made a quick trip to Moscow to assure Putin that what he thinks about the EuroMaidan Revolution is wrong. Moreover, considering the enormous debts that Ukraine owes to Russia, as well as the deep historical, cultural and economic ties, a sovereign Ukraine still needs to understand that the two nations are inextricably linked.
4. Passing a language law that downgraded Russian from its previous status as an official language. This is really, really bad timing and pointless amid a national crisis, aside from the fact that the law ignores the reality that much of the nation still prefers to speak Russian.
Putin's grand mistake, however, may work out in Ukraine's favor soon in at least three ways.
For one, the West should come to realize, once and for all, that there's no doing business with Putin. As long as he keeps the finger off the nuclear weapon trigger, another Cold War against him is fine and will help the world if it leads Russians to get rid of him also.
Secondly, Yulia Tymoshenko is back on the case. As despised as she is by some people, the newly freed former prime minister knows how to talk to Putin and rally her nation. Look for tactics that are more Gandhi than Ghengis Khan.
Thirdly, Ukraine's EuroMaidan Revolution masked a lot of divisions by the participants that now seem petty in comparison to the need to defend the nation's sovereignty from attack.
But clearly Ukraine's new interim leaders and the West, led by U.S. President Barack Obama, need to do more. Their weak rhetoric backed up by even weaker action gave Putin the opening that he needed -- and that he rammed thousands of his own soldiers through.
When I heard Obama talk about "costs" to Russia of a military intervention in Ukraine on Feb. 28, I cringed a bit because I thought he was just talking tough and saying the right words without having a real plan. Soon we will see. The time for statements of outrage are over. More actions, such as the Swiss and Austrian seizures of assets of former Ukrainian officials, are needed.
If the West is going to ride to Ukraine's rescue, now is the time to do it. Ukrainians are justifiably proud of the heroism they displayed over the last three months. But they will have to rise to a level of heroism now that perhaps they never imagined. In this struggle, democratic nations need to be at their side. This is one battle in which victory will require a united effort.
