Iran's Nuclear Program: The Larger PictureThere is a bigger question that why Iran - a country with large oil reserves feels such a need to have home-grown civil nuclear energy? Further, it also puzzles one with Iran’s obsession with continuing a nuclear program. US President Donald Trump has repeatedly said the US attack on Iran obliterated its nuclear program and prompted the ceasefire. However, a US official briefed on the Defence Intelligence Agency’s initial assessment told USA TODAY the core components of Iran’s nuclear program appeared to remain intact. The nuclear program can be rebuilt, he said, but he declined to put a timeline on it.
