Obama and Kerry sacrificed the pursuing of Hezbollah's global drug trafficking ring through central America and into the USA.

Hezbollah funds terror by selling drugs (cocaine) in the USA and laundering money through used cars sent from the USA to Africa. Iran told Obama that there would be no Iran deal if the DEA didn't back off the drug dealers. John Brennan (politico article) stood up for Hezbollah because he says they are a reformed political party in Lebanon who helps the poor. Terrorists and drug dealers who claim to help the poor - sounds a lot like Democrats.
