For First Time, Kremlin Signals It Is Prepared to Annex Crimea

Russia signaled for the first time on Friday that it was prepared to annex Ukraine’s Crimea region, significantly intensifying its confrontation with the West over the political crisis in Ukraine and threatening to undermine a system of respect for national boundaries that has helped keep the peace in Europe and elsewhere for decades.

Leaders of both houses of Russia’s Parliament said that they would support a vote by Crimeans to break away from Ukraine and become a region of the Russian Federation, ignoring sanction threats and warnings, from the United States and other countries, that a vote for secession would violate Ukraine’s Constitution and international law. The Russian message was yet another in a series of political and military actions undertaken over the past week that outraged the West, even while the Kremlin’s final intentions remained unclear.

As fresh tensions flared between Russian and Ukrainian forces in Crimea, the moves by Russia raised the specter of a protracted conflict over the status of the region, which Russian forces occupied last weekend, calling into question not only Russia’s relations with the West but also post-Cold War agreements on the sovereignty of the nations that emerged from the collapse of the Soviet Union.

The referendum — barely a week away — has been denounced by the fledgling national government in Kiev, which said it would invalidate the outcome and dissolve the Crimean Parliament. President Obama has also rejected the referendum, and the United States government announced sanctions on Thursday in response to Russia’s de facto military occupation.

Russia denounced those sanctions in a blunt rejoinder on Friday evening, posted on the Foreign Ministry website. The statement said that Russia’s foreign minister, Sergey V. Lavrov, had spoken by telephone with Secretary of State John Kerry and warned that “hasty and ill-considered steps” to impose sanctions on Russian officials “would inevitably backfire on the United States itself.”
