The promises made about non-expansion of NATO, about not building military infrastructure in the east, and no deployment of significant combat forces on the territory of new members, were simply rudely thrown into a bin by the West.
During the five waves of NATO expansion, the Alliance has come to the borders of Russia. Now it is actively developing these territories militarily, building up ground forces, aviation, increasing the scale of exercises in the Black Sea. All of these current actions of the West grossly violate the obligations previously assumed.
