Who is being armed in the Middle East?

"With the removal of sanctions, Iran is eager to modernize its military and keep pace with its regional rivals through purchases of foreign arms. Iran is surrounded by some of the world’s largest importers of advanced conventional weapons systems, including Israel, Saudi Arabia, the United Arab Emirates, Qatar, and Pakistan. Iran is also faced with a heavy U.S. military footprint in the form of a network of military bases and deployments of air and naval assets that serve to contain and deter its actions. Given its security environment, it is no surprise why Iran has prioritized the modernization of its conventional military capabilities following the implementation of the JCPOA. " (thanks Pierre)
