The risk of Moscow using nuclear weapons in the Ukraine conflict has diminished because the international community "has drawn a red line" at Russia, according to German Chancellor Olaf Scholz."For the time being, we have put a stop to it," said Scholz, referring to the risk of a nuclear escalation.Scholz believes his recent trip to China is part of the reason behind the apparent lessening of the nuclear weapons threat from Russia.Asked about the recent controversy triggered by French President Emmanuel Macron, who felt that Russia should be given "guarantees" to find a good balance once the war in Ukraine was over, Scholz acknowledged that in the long run the question of the security architecture would arise.The Russian president however said "the threat of a nuclear war is growing", given the Russia-West confrontation over Ukraine, blaming the Americans and Europeans."
