Excerpt:
In an interview with Jeffrey Goldberg of The Atlantic, President Obama laid out key elements of his approach to foreign policy. There is much in it with which one can agree. “Don’t do stupid s——” makes sense as an axiom of foreign policy—or of any policy, for that matter—as does taking deliberate and strategic decisions about when to engage American military power.
As regards the two-year-old conflict between Ukraine and Russia, the president said Ukraine is a core interest for Moscow, in a way that it is not for the United States. He noted that, since Ukraine does not belong to NATO, it is vulnerable to Russian military domination, and that “we have to be very clear about what our core interests are and what we are willing to go to war for.”
It is hard to dispute these points…except that the president set up a straw man. The United States could have done more to help Kyiv resist the Kremlin’s aggression without a war with Russia.
Why care about Ukraine?
There are critical reasons for Washington to support Ukraine. The Kremlin is pursuing a revisionist policy designed to undermine the post–Cold War order established in Europe. Vladimir Putin claims a right and duty to intervene to protect ethnic Russians and speakers wherever they live and regardless of their citizenship. He used that as a justification to invade Georgia in 2008 and Ukraine in 2014. 25 percent of the populations of two NATO member states—Estonia and Latvia—are ethnic Russians. Recent Russian provocations in the Baltic states include kidnapping an Estonian counterintelligence official on the final day of the last NATO summit. Making Putin pay a heavy price for his aggression in Ukraine makes it less likely that he will commit further provocations in the Baltic states. Such provocations could lead to miscalculations and the war that President Obama wants to avoid.
Moreover, in 1994, the leaders of the United States, Britain and Russia signed the Budapest Memorandum, in which they committed to respect Ukraine’s sovereignty, independence and territorial integrity and pledged not to use force against that country. That memorandum was key to Kyiv’s decision to give up nearly two thousand strategic nuclear warheads and the associated strategic missiles and bombers. This was a major victory for U.S. policy, and for nonproliferation. Moscow’s violation of this agreement is a strong disincentive for future nations to give up weapons of mass destruction. The Obama administration rarely mentions the Budapest Memorandum, but that memorandum answers the “why should we care?” question that Obama implied in his interview with Goldberg.
What should Washington do? It should keep providing Kyiv political support, and work with the European Union to offer additional financial assistance, provided that Ukraine accelerates reforms and anti-corruption measures. It should also provide additional military assistance.
On the last point, we are two of eight coauthors of a report issued early last year—“Preserving Ukraine’s Independence, Resisting Russian Aggression: What the United States and NATO Must Do”—that argued for providing Ukraine additional military assistance, including light antiarmor weapons. Those were intended to fill a gap when the Russian military was pouring tanks and other armored vehicles into the Donbas.
The administration rejected lethal military assistance. In our meetings last year with senior U.S. officials, it was apparent that the White House’s main concern was escalation: that the Russians might out-escalate the United States, or that U.S. leaders would find themselves on an escalation ladder that would end up with the Eighty-Second Airborne Division deploying to Donetsk.
