After Vladimir Putin's speech in the Kremlin justifying and welcoming Russian annexation of Crimea, the Western press now asks what next will Putin do? How far will he go?

That question was answered by Vladimir Putin himself in his address. The Russian president said his country has no further demands to make on Ukraine. Crimea became an issue because the West "crossed a red line," a reference to American and European efforts to bring Ukraine into the North Atlantic Treaty Organization (NATO), which they renounced in exchange for Russian agreement to German unification.

The Ukrainians — the Ukrainian-speaking Westerners at least — don't believe that Putin intends to go no further. Ukraine's new prime minister, Arseniy Yatsenyuk, back from Washington, declared that Putin now "threatens the entire world."
