Russian aggression remains very much in the headlines, as President Vladimir Putin last week re-opened the southern front and more recently reportedly bragged that he could capture the Ukraine in just a couple weeks. Max Boot rightly writes that the gestures NATO envisions won’t deter Putin. The problem with American and perhaps NATO policy goes deeper, however.

So much policy in recent years has been based on wishful thinking. Obama and Secretary of State Hillary Clinton preferred to see problems in U.S.-Russian relations as rooted more with their predecessors than with Putin himself, hence the investment in the “reset.” There continued years of denial about Putin’s true intentions, all the while making compromises and offering concessions based on the deluded notion that Putin was more partner than pariah. When Putin invaded Crimea, when he shot down Malaysian Airlines flight 17, and when he continued his push into his neighbor, Obama simply reacted with a patchwork of statements and superficial pronouncements until the television cameras moved on. Indeed, if there is one core principle to the Obama doctrine, it is not leading from behind (for that would imply leading), but rather simply reacting to world events in a scattershot fashion.

It’s time to be proactive. Putin can boast that he can take the Ukrainian capital Kiev in two weeks, but he really doesn’t need to. After all, Ukraine remains overwhelmingly dependent upon Russian gas shipments to power its factories and heat its homes during the winter. If Putin simply turns a nozzle, he can freeze Ukrainians into submission. Everyone sees the winter coming, and yet there does not appear to be much planning within U.S. policy circles about how to prevent Russian hardball with energy shipments.

It’s time to talk about a “Berlin Airlift” of escorted shipments of fuel into Ukraine. Such an operation would be difficult, but then again, so was the Berlin Airlift. American warships can enter the Black Sea on routine patrol, and Romania can contribute and provide basing and logistical support, if not active partnership. If the United States could reflag Kuwaiti tankers to protect them, so too could the United States re-flag tankers bound for the Ukraine.

There is no doubt that any Ukraine flotilla would be expensive. It is also true that European officials—and especially Chancellor Angela Merkel in Germany—construct their policies more on mercantile considerations than on principles. But then again, if economics always trumped freedom, there would have been no Berlin Airlift and the Cold War would have taken a far worse turn. But looming problems require more than posturing and press conference; they require proactive resolutions. Alas, time is running out to construct such a solution and to prevent Putin from transforming Ukraine into the vassal he envisions.
