US Democratic Representative Bill Foster warned US President Donald Trump of the consequences of fulfilling his campaign promise to dismantle the Iran nuclear deal.

“What I hope has happened is that whoever is having conversations with the president said, ‘If you follow through with your campaign promise to walk away from deal, within one year or maybe two we will be facing the choice of nuclear-capable Iran or a war,” Foster told the Hill on Friday.

Iran denies the charge that its nuclear activities may have had any military aspects, stressing that the program is only for civilian purposes.

Foster, the only member of Congress with a doctorate in physics, penned a letter to Trump arguing the US, Israel and the world are safer today because of the nuclear deal.

He also outlined the steps Iran has taken to comply with the deal, including removing two-thirds of its installed centrifuges, reducing its stockpile of enriched uranium by 98% and filling its heavy water research reactor with cement, making it inoperable.

However, political washouts like John Bolton, the former US ambassador to the UN, seek to revive their fortunes by criticizing the nuclear deal. Bolton is obviously blind to Iran’s commitment toward and compliance with the nuclear deal, which has been confirmed by the International Atomic Energy Agency, and wants Trump to step away entirely.

“Every day that goes by weakens our position. I think Iran never had the slightest intention to comply with its main provisions,” Bolton claimed in a separate interview with the Hill.

Foster’s letter to Trump was signed by 60 Democrats, but no Republicans.
