[snip] The United States has historically been a major supplier of weapons to the Saudi monarchy. Former President Donald Trump maintained close ties with Riyadh, aiming to bolster the regime against Iran. His arms sales to the Saudis prompted congressional rebuke and Trump subsequently vetoed measures to block arms sales to the country. President Joe Biden, however, reversed course and suspended arms sales to Saudi Arabia and the United Arab Emirates this year. [/snip]
There have been reports here in FR that anti Saudi ISIS was given some of the US arms and also that Iran had sent its troops to get some while sent to teach the Tbans how to use them.
