Today, Reps. Peter Roskam (R-IL) and Ted Deutch (D-FL) urged Secretary of State John Kerry to work to prevent the sale of advanced S300 surface-to-air missiles by Russia to Iran. The letter to Secretary Kerry comes amid reports of a new Russia-Iran defense agreement that includes the transfer of S300 air defense systems.
"We write to express our concern over recent media reports that Russia may again be considering supplying five S300 advanced air defense systems to Iran," the lawmakers write in the letter. "This unwelcome news of the potential sale comes as Russian Defense Minister Sergei Shoigu concludes a visit to Tehran where he and Iranian Defense Minister Brigadier General Hossein Dehqan reportedly signed an agreement to boost defense cooperation between Russia and Iran We remain concerned that the S300 systems would significantly expand Iran's defense capabilities, potentially emboldening Supreme Leader Khamenei's pursuit of nuclear weapons."
Roskam and Deutch expressed concern about a previous potential S300 transfer from Russia to Iran in a letter sent to Secretary Kerry in September 2013. The sale was never completed.
