The tense atmosphere inside the UN General Assembly hall began building immediately before Israeli Prime Minister Benjamin Netanyahu approached the rostrum. Prompted by a coordinated call from the Palestinian Mission urging member states to protest, scores of diplomats and international delegates staged a mass walkout. Rather than sitting through an address they viewed as an attempt to sanitize ongoing humanitarian devastation, representatives left large sections of the assembly hall visibly empty. Those who remained were met with a chaotic mix of loud boos, jeers, and counter-cheers, setting a confrontational tone for the proceedings even before the premier uttered a single word.Why Did Netanyahu Call Gaza Genocide Accusations "The Biggest Lie"?Taking to the podium amidst the uproar, Netanyahu delivered a combative speech that directly addressed international legal accusations and global criticism. He forcefully dismissed allegations of genocide in the Gaza Strip, labeling them "the biggest lie of the century" and arguing instead that Israel's military operations were designed to prevent further atrocities. Backing his stance with comparisons to historical conflicts and pointing to military strategies, he claimed his forces maintain an unprecedented standard of conduct under extreme duress. He further condemned the diplomats who abandoned the hall, labeling them "moral cowards" and asserting that their home nations secretly acknowledge the necessity of Israel's security campaigns.How Did Regional Tensions and Iran Factor Into His Speech?Beyond the ongoing conflict in Gaza, Netanyahu used the global stage to address broader geopolitical friction in the Middle East, most notably regarding Iran. He described military actions against Iranian nuclear infrastructure as one of the most critical and straightforward decisions of his tenure, emphasizing that these strikes served to protect Western nations as well as Israel. He alleged widespread international hypocrisy, claiming that various foreign leaders privately expressed gratitude for neutralizing threats that endanger regional stability. This rhetoric underscored a wider diplomatic battleground, juxtaposing Israel's insistence on unilateral self-defense against escalating calls from Arab and European leaders for immediate ceasefires, accountability, and the establishment of a pathway toward Palestinian statehood.also read : Saudi Oil Surge Pushes Gulf of Oman Transfers to Max
