Nuclear war: UN Secretary-General says nuclear conflict could happen with Russia

UN Secretary-General Guterres says the prospect of a nuclear conflict is, "back within the realm of possibility." This comes as Russia's latest attacks in getting closer to NATO countries like Poland. The fear of a deadly escalation in the conflict has been at the center of the Biden administration's response in recent days, with the Pentagon last week denying a request from Ukraine to transfer Polish MiG-29 fighter jets to the country's armed forces through the U.S.'s Ramstein Air Base in Germany.
