Hassan Rouhani answers a question during a press conference in New York on September 20, 2017.

:: President Hassan Rouhani vowed on Friday that Iran would boost its ballistic missile capabilities despite criticism from the United States and also France.

“Whether you like it or not, we are going to strengthen our military capabilities which are necessary for deterrence,” Rouhani said in a speech marking the anniversary of the outbreak of Iran’s devastating 1980-1988 war with Saddam Hussein’s Iraq.

“We will strengthen not only our missiles but also our air, land and sea forces… When it comes to defending our country, we will ask nobody for their permission.” Criticism by the Donald Trump administration of a 2015 nuclear deal between Iran and major powers, including the United States, has focused heavily on Tehran’s continuing missile program.

Nuclear warhead

Tehran says that the missiles are entirely legitimate under the terms of the deal as they are not designed to carry a nuclear warhead. But Washington says they breach the spirit of the agreement as they have the potential to carry a nuclear warhead and has imposed new sanctions over Tehran’s continuing launches and tests.

But Trump, who this week described the deal as an “embarrassment”, is due to report to the US Congress on October 15 on whether or not he believes that Iran is in compliance. If, as now appears increasingly likely, he decides that it is not, it could open the way for renewed US sanctions and perhaps the collapse of the agreement.

Trump said on Wednesday he had made his decision but was not yet ready to reveal it. Washington has also taken aim at what it says is Tehran’s failure to meet expectations that it would play a more stabilizing role in the Middle East.

“Regrettably, since the agreement was confirmed we have seen anything but a more peaceful, stable region and this is a real issue,” Secretary of State Rex Tillerson told reporters at the United Nations.
