where is the evidence? its everywhere. nato has doubled in size since the cold war ended expanding into eastern europe and along russias borders. in response to what? how many nations have joined the ussr military alliance expanding into western europe and along the borders of the united states, canada and other nato allies in western europe? these nations in eastern europe do nothing to contribute to the security of western nations, they contribute nothing to nato other then territory on which nato can build military bases and missle sites closer to russia. mutual destruction is what has kept the peace, if nato surrounds russia that will no longer be the case. nato expansion into eastern europe does nothing to secure peace, it removes the main deterrent against all out nuclear war.
