many of the Houthis’s weapons were manufactured in Europe and the United States in the first place

"One cable from the United States-Canada Embassy in Sana’a on December 9, 2009, reads: “Contrary to [Republic of Yemen Government] claims that Iran is arming the Houthis, most analysts report that the Houthis obtain their weapons from the Yemeni black market and even from the [Republic of Yemen Government] military itself.” The Houthis still get many of their weapons from these sources, despite possible Iranian backing. The brutal irony is that many of the Houthis’s weapons were manufactured in Europe and the United States in the first place."
