The Israel-Gaza war could possibly spread to become a wider regional conflict and drag in more countries amid the war in Ukraine and other geopolitical tensions, leading to World War 3, Israeli writer and historian Yuval Noah Harari told NDTV's Sonia Singh in an exclusive interview today. Global instability is high after the COVID-19 pandemic, the war in Ukraine and now the Israel-Gaza war that risks pulling in more nations into it, eventually leading to conditions that could spark a global war, Mr Harari said.
