It seems that NATO countries, and especially the United States, have developed a peculiar understanding of security which is fundamentally different from our view. The Americans are obsessed with the idea of securing absolute invulnerability for themselves, which, incidentally, is a utopia, for both technological and geopolitical reasons. But that is exactly where the root of the problem lies.
Absolute invulnerability for one nation would mean absolute vulnerability for everybody else. We cannot agree to this. Of course, many nations prefer not to raise this question openly for a variety of reasons. But Russia will always call a spade a spade and speak openly about such matters. I would like to stress once again that violation of the principle of common and indivisible security (accompanied by repeated assurances that they are still committed to it) may have extremely serious consequences. Sooner or later, those consequences will also affect the nations that initiate such violations, whatever their reasons are.
Absolute invulnerability is also impossible. Pursuing it is insane; as such is it any surprise the USG is the mad dog of the world?
