US President Donald Trump on Tuesday said Iran would face bigger problems if Tehran restarts its nuclear program. He also called the nuclear accord with Iran “insane,” Reuters reports. “They will have bigger problems than they have ever had before,” Trump said of Iran. He was speaking at the start of a White House meeting with French President Emmanuel Macron, who told reporters he wants to contain Iran in the region. Iran’s Supreme National Security Council said earlier on Tuesday that Tehran might withdraw from the nuclear Non-Proliferation Treaty (NPT) if Trump scraps the nuclear deal Tehran and world powers signed in 2015.
