I certainly don't think the cold war is war, but I want to remind you that it involved many countries. On the side of America, all NATO countries, and on the side of the Soviet Union all the countries of the Warsaw Pact.
In a short while the cold war 2.0 will start. The chances are bright, especially after the Americans destroyed a Syrian air base almost an hour back. IMO, this will be the composition of the warring sides:
NATO+: USA, EU, Japan, South Korea, GCC, Pakistan, Turkey.etc
Russia/China+: Russia, China, DPRK, Iran, Belarus, South Africa.etc
