Well 'terrorists' would easily be a higher threat depending on where they are.
Why so? Because depending on where they are, a country might want to 'sponsor' them in order to gain some control of the lands in that area. As a theoretical example (as in, my dad told it to me but i have no proof to back this as being fact): lets say that Sudanese militia needed weapons, preferably the losing team. Now lets add that sudan (in theory) has major oil supplies, and that china needs more oil exploits. China could give guns to a side, and in return would have access to some of that team's conquered lands.
However for a stable nation, they have to rely mostly upon themselves, whereas 'undeveloped' nations suckle off of other countries in order to get the things that they need.
Also, in order to get MAJOR damage weapons, a country's scientists could easily go to a different country and get information from them, and then apply it back in their home country.
