Cartels would be idiots ruining their main cash cow, the USA.

If anything, I'd think that cartels would be fighting against them.

Yep. I can't think of a single benefit to the cartels aligning themselves with ISIS. But there's a whole lot of negatives. The cartels are businesses. Why would they purposely attract the attention of the US military or want to destroy their customer base. Why would they want a massive increase in border security? As Cartman said, it doesn't make sense.
