A 13-year United Nations ban on Iran's ability to buy and sell conventional arms expired on Sunday over the objections of the U.S, which insisted that all UN sanctions on Iran had been reimposed under the "snapback" process of the 2015 nuclear agreement — even though President Trump withdrew from the deal in 2018.
Why it matters: The expiration of the arms embargo will allow Iran to buy advanced weapons systems from countries like Russia and China, upgrading military equipment that dates back to before the 1979 Islamic Revolution, according to the AP.
