`The goal is for the sake of the peace of future generations of Ukrainians themselves and the opportunity to finally build an open Eurasia - from Lisbon to Vladivostok.'

Considering that the phrase "Lisbon to Vladivostok" isn't new, and has previously refered to economic integration, I would say taht interpreting this as a threat of war or empire (as for example MSN does) is to put too much into it.
