"In a letter sent to the governments of Poland, Romania and Hungary, Vladimir Zhirinovsky also suggested those countries hold referendums on incorporating the regions into their territory. Zhirinovsky, whose nationalist Liberal Democratic party largely backs President Vladimir Putin in the Russian parliament, sent the letter as Russia annexed the Crimea region of southern Ukraine last week. He is deputy speaker at the Duma and his party holds a minority in the parliament. But his ideas and language resonate with a large part of the Russian population and the Kremlin's increasingly pro-nationalist rhetoric. His letter, seen by Reuters, suggested Poland, Hungary and Romania, who are now in the European Union, might wish to take back regions which he said were in the past their territories." Reuters
So, basically, this political ally of the Russian president has invited Poland, Hungary and Romania to exercise supposed irredentist claims against the Ukrainian state created by the Soviet Union as a result of soviet victory in world War 2.
The borders of the territories in eastern Europe have ben moving around for many centuries. In many cases the present borders are of recent invention. The notion that they are somehow engraved on stone tablets in some distant Olympian vault never to change again is laughable to anyone who knows any history at all.
It will be interesting to see if this idea is attractive to the Polish, Hungarian and Romanian peoples as opposed to their governments. pl
