From today's Wall Street Journal:
Still, there is no better place to cause a political crisis in Ukraine and force a change in the country's leadership, already locked in a bitter internecine struggle, than the Crimean peninsula. It was wrestled by Catherine the Great from the Ottoman Turks at the end of the 18th century. Less than a quarter of the Crimeans are ethnic Ukrainians, while Russians make up over half the inhabitants (the pro-Ukrainian Crimean Tatars, one-fifth).
Ever since the 1997 Treaty of Friendship and Cooperation between Russia and Ukraine, signed by President Boris Yeltsin and Ukrainian President Leonid Kuchma, a solid majority of the Russian parliament has opposed the recognition of the Crimea as Ukrainian territory. Russian nationalists have been especially adamant about the city of Sevastopol, the base for Russia's Black Sea fleet and the site of some of the most spectacular feats of Russian military valor and sacrifice in World War II and the Crimean War of 1854-55.
Nationalist politicians, including Moscow Mayor Yuri Luzhkov, have repeatedly traveled to Crimea to show the flag and support the Russian irredentists -- many of them retired Russian military officers who periodically mount raucous demonstrations. In 2006, their protests forced the cancellation of the joint Ukraine-NATO Sea Breeze military exercises. Sevastopol was and should again be a Russian city," Mr. Luzhkov declared this past May, and the Moscow City Hall has appropriated $34 million for "the support of compatriots abroad" over the next three years. On Sept. 5, Ukraine's Foreign Minister Vladimir Ogryzko accused the Russian consulate in the Crimean capital of Simferopol of distributing Russian passports to the inhabitants of the peninsula.
With almost three-quarters of Sevastopol's 340,000 residents ethnically Russian, and 14,000 Russian Navy personnel already "on the inside" (they've been known to don civilian clothes and participate in demonstrations by Russian Crimean irredentists), an early morning operation in which the Ukrainian mayor and officials are deposed and arrested and the Russian flag hoisted over the city should not be especially hard to accomplish. Once established, Russian sovereignty over Sevastopol would be impossible to reverse without a large-scale war, which Ukraine will be most reluctant to initiate and its Western supporters would strongly discourage.
A potentially bolder (and likely bloodier) scenario might involve a provocation by the Moscow-funded, and perhaps armed, Russian nationalists (or the Russian special forces, spetznaz, posing as irredentists). They could declare Russian sovereignty over a smaller city (Alushta, Evpatoria, Anapa) or a stretch of inland territory. In response, Ukrainian armed forces based in the Crimea outside Sevastopol would likely counterattack. The ensuing bloodshed would provide Moscow with the interventionist excuse of protecting its compatriots -- this time, unlike in South Ossetia, ethnic Russians.
Whatever the operational specifics, the Russian political barometer seems to augur storms ahead.
