Hezbollah is an international radical group. Hezbollah is involved in drug trafficking in Bolivia, And moves opium from the Middle East (the golden crescent Afghanistan) and money from South America collected from the Bolivarian revolutionaries. This is an integral part of the global narcotics trade, And also helps to fund Russias war in Ukraine and Chinas synthesis of precursors to Fentanyl. So the long answer is the Bolivars paid for those missiles in drug money. Check out the Iran Contra scandal. Intelligence services have used drug money to fund many black ops around the world due to a lack of accountability.
