Donald Trump has issued a strong warning against Iran’s nuclear ambitions, saying the world “cannot let Iran have a nuclear weapon.” Trump claimed that allowing Iran to develop nuclear capabilities could trigger a massive conflict in the Middle East, with repercussions spreading to Europe and beyond. Calling it the “most important” global security issue, Trump said the risk of a wider nuclear war cannot be ignored. His remarks come amid rising geopolitical tensions, growing concerns over Iran’s nuclear program and renewed focus on stability in the Middle East. Trump’s statement is likely to intensify the global debate around security, diplomacy and the possibility of fresh confrontation involving Iran and Western powers.
