History is repeating itself.
During the period 1939-1941, USSR prepared for war by annexing territories which would later be used strategically.
The same thing is happening now.
NATO (as a military entity/alliance) should have been dissolved decades ago; to bring Poland, the Czech republic and Hungary into NATO and to extend its borders all the way to the Prut river during the 1990s, meant only one thing: a future war Nato/Russia was planned from the very start (1990).
