Iran has pursued nuclear weapons for over four decades. The basic reasons for this quest have remained unchanged in the face of the most crippling sanctions. Almost three and a half years after Trump’s withdrawal from the Iran Nuclear Pact (JCPOA), Tehran officially announced that it has enriched uranium up to 60%, very close to the 90% suitable for nuclear weapons. Iran is highly likely to be the world’s next nuclear state. A nuclear-armed Iran will be emboldened to accelerate its aggressive activities in the region and act against its neighbors with little fear of retribution. Moreover, Iran’s network of proxies would adopt a more confrontational approach towards Israel. Besides, Iran’s politics of threat can have serious socioeconomic consequences for Israel.Iran’s possession of nuclear weapons could arguably set off a cascade effect, encouraging other major regional powers to move in the same direction. The West, particularly the United States, would seek to offset this risk by providing a “defenceumbrella”.
