Alzbeta Ehrnhofer was a 13-year-old Slovak schoolgirl when the Soviet Army poured into Czechoslovakia to "restore order" after the 1968 Prague Spring promised some freedoms to the Warsaw Pact nation.

The unfolding crisis in Crimea blaring from the television in Ehrnofer's Vienna apartment Monday transported her back almost 46 years ago, when army-green tanks rumbled past her house in the southern Slovak town of Filakovo, near the Hungarian border, and neighbors hid from Russian-led invaders.

"It's just like it was here in 1968," she said about the upheaval in Ukraine, a former Soviet republic undergoing its second revolution as an independent nation. "Nothing's changed. Even the tanks look the same."
