President Trump said: ”I don’t think Iran is in compliance.
“I don’t think they’re living up to the spirit of the agreement.”
In 2015 Iran signed a nuclear deal with the United Nations, under former president Barrack Obama, restricting its use of uranium – a key ingredient in atomic weapons.
An official, who declined to be named, likened Iran’s missiles to North Korea’s rocket amid World War 3 fears, as he added: “When those midget subs are operating underwater, they are running on battery power, making themselves very quiet and hard to detect.”
Meanwhile Jeffrey Lewis, a missile proliferation expert at the Middlebury Institute of International Studies at Monterey, in California, said: “The very first missiles we saw in Iran were simply copies of North Korean missiles.
“Over the years, we’ve seen photographs of North Korean and Iranian officials in each other’s countries, and we’ve seen all kinds of common hardware.”
He added: “In the past, we would see things in North Korea and they would show up in Iran.
“In some recent years, we’ve seen some small things appear in Iran first and then show up in North Korea and so that raises the question of whether trade – which started off as North Korea to Iran – has started to reverse.”
Yesterday, Pyongyang announced a plot to launch four missile at US-owned Guam within days.
A state media spokesperson, citing General im Rak Gyom, commander of the Strategic Force of the KPA, said: “The Hwasong-12 rockets to be launched by the KPA (Korean People’s Army) will cross the sky above Shimane, Hiroshima and Koichi Prefectures of Japan.”
It follows a warning from Trump that North Korea would be met with “fire and fury” if the rogue state continued to threaten America.
Last month the Republican had been forced to back off from a key campaign promise to withdraw from the nuclear deal with Iran.
Trump had described it as “the worst deal ever” and slapped fresh sanction on the Islamic Republic – targeting 18 individuals and entities over its ballistic missile programme.
Earlier this year, Secretary of State Rex Tillerson warned Iran may head down the same path as North Korea if left unchecked by world leaders.
Mr Tillerson accused Iran of supporting terrorism, including providing weapons and funding to Hamas and other Palestinian terror groups.
He said: “Whether it be assassination attempts, support of weapons of mass destruction, deploying destabilising militias, Iran spends its treasure and time…
