Cartels and spics don't even come close jfl. The closest is maybe the IRA but still far behind @imontheloose

I just realized that ur list is about "deadliest", which makes sense I guess. But if it was about the most powerful (as in who would win in an all out war), would the list still pretty much be the same?

Taliban, ISIS, Al-Shabaab, Hamas, Boko Haram, TTP stay high in taking due to raw numbers fuel power. But Hezbollah and also Houthis jump via state sponsors (Iran) and advanced weapons.
