Russia is not a threat to the whole Earth, it's maybe a threat to USA and USA is not the whole world. What is a real threat is this non-stop passive-agressive conflict between these two countries.
Us Senator John McCain has promised to make all efforts to find different ways to introduce new sanctions against the Russian Federation. "We will consider other options, including within the framework of the Senate Committee on armed forces," McCain said. According to him, delaying the introduction of new sanctions only emboldens the President of Russia Vladimir Putin.
"It's time to take real measures, including the strengthening of sanctions to punish destabilizing behavior of Russia and to counteract its malign influence", concluded McCain. You think McCain does not understand the situation? Sure he knows more than you.
