Confront the US and its vassals with the fact that neither Russia nor the US and its allies believe one word of the accusations which are intended to serve Washington's hegemony by marginalizing and isolating Russia.
Confront the US and its vassals with the fact that similar demonizations of Saddam Hussein, Gaddafi, and Assad led to military invasions of their countries. Ask if the US and its vassals are preparing their populations for a military attack on Russia.
Confront the US and its vassals with the fact that the tension between the nuclear superpowers is far higher than during the Cold War of the 20th century and that the lies and mendacity of the US government have completely destroyed Russian trust in Washington.
Confront the US and its vassals with the fact that during the Cold War there were numerous false warnings of incoming enemy ICBMs, but that as the two governments were working to reduce tensions, neither side believed the warnings, whereas today the situation is far different. In view of the extraordinary hostility displayed toward Russia by the US and its vassals, Russia cannot take a chance that a warning is false. As the US and its vassals are targeted by Russian nuclear forces, the West has the world on a course of destruction. Is this what Washington and its vassals want? Is the choice Washington's hegemony or death? Ask Washington's vassals why they support this insane choice.
For so long Americans have laughed at the cartoon picture of the bearded man holding his sign, "The End Is Near," that Americans probably cannot intelligently respond to a warning no matter who gives it.
Similarly, Western policymakers are so demented and the presstitute media so corrupt that the response to a Russian approach to the UN as outlined above would be used as proof of the West's anti-Russian propaganda. The headlines would read: "Russia Threatens the World With Nuclear War."
Therefore, it seems that the only alternative is for Russia to turn her back -- but not her eyes -- on the West and to find her future in the East.
All indications are that Russia is unwilling to do this. It seems that for the Russian government, being a part of the West is more important than life itself.
