From the Drug Enforcement Administration to the Mexican government to Donald Trump, the list of people not invited to a Joaquin "El Chapo" Guzman party isn't short.
And it just got longer.
It appears one of the world's most powerful drug traffickers is now facing off with one of the world's most feared terrorist organizations - ISIS.
According to a letter allegedly leaked to Cartel Blog, several drug shipments belonging to the Sinaloa Cartel were destroyed while being transported through the Middle East.
In the alleged letter, Guzman states "Your god cannot save you from the true terror that my men will levy at you if you continue to impact my operation."
