A Russian invasion of Ukraine would be devastating, and a wider European war even worse. Whether a larger war happens would depend partly on President Vladimir Putin's ambitions, partly on the West's military response, and partly on plain luck.
Although U.S. and European officials have said for days that a Russian invasion appeared imminent, Putin’s government on Tuesday publicly welcomed further security talks with the West. It also announced that some of its forces bracketing Ukraine will be returning to their regular bases, although U.S. and other Western officials said it was too early to tell whether the invasion threat had receded.
