World News : Biden's statement gives alarming signs; The threat of the use of nuclear weapons looms large

US President Joe Biden has expressed his fears related to the Ukraine war. Biden has said that Russian President Vladimir Putin's threat to use nuclear weapons in Ukraine has drawn the world closer to a world war. The serious threat of a world war has arisen for the first time since the Cold War era tensions over the deployment of Soviet missiles in Cuba. Biden has said that Putin may use nuclear weapons in Ukraine in the face of defeat.

The threat is the most serious since then-Soviet leader Nikita Khrushchev's decision in 1962 to deploy missiles in Cuba close to the US border. In protest against this missile deployment, the then US President John F. Kennedy had warned of the outbreak of world war. Later that issue was dropped.

Biden said, for the first time since the Cuban Missile Crisis, the world is feeling the danger of using a nuclear weapon. If the situation continues to deteriorate like this, then this danger may turn into reality. Biden said Putin's statement about the use of tactical nuclear weapons or biological weapons or chemical weapons is not a joke.

Ukrainian President Volodymyr Zelensky has said that his security forces have taken back 500 square kilometers of territory from Russian forces this week. Ukrainian forces are also fighting in Donsk, Kherson and Zaporizhia, which Russia has recently joined.
