Actually, when one looks at African and Middle Eastern countries, as opposed to eastern Europe and/or the former Soviet Union, a lot of folks DO have guns. Even after we had a semblance of control in Iraq, households were still allowed to have a Kalashnikov for personal use and protection of the home.
But the reasons why (what we think are) good things haven't always come from that are as varied as the countries themselves.
The middle eastern countries tend to follow tribal (very extended family in other words) loyalties, much more than official country loyalties, by and large. Some tribal or cultural groups do resist even violent dictators from time to time. (Look at the Kurds.) Some wouldn't fight (usually, except when making a power play) because they are part of the ruling tribe/family. Others manage to find their place in the status quo and have just enough autonomy and what they consider to be quality of life that they won't rock the boat. And these places tend to foster, follow and even respect very direct, brutal rulers as that's all their cultures have ever known and all they ever really foresee. Not so much a fight for your rights as a group deciding that they either must overthrow or submit and make the best of it... and they realize they cannot overthrow.
In many African countries there are a LOT of guns, but they aren't in the hands of the masses, so to speak. Instead they're in the hands of large groups of thugs, militias, and armies ruled over by warlords for power and profit. When you and hundreds of thousands of your neighbors are all scrambling for a few grains of rice a day and a multi-mile walk for a jug of dirty water, even when an AK only costs a few bucks, if you had one you'd sell it for food. Instead of the heads of households being responsible armed citizens, the armed are often children, deliberately orphaned, heavily drugged, given power over others by genocidal big men like Joseph Kony, or smaller-time criminal kingpins operating in the diamond industry.

The eternal question is how would any of that relate to a rich, comfortable, well-fed technologically advanced society with a powerful central government based on a federal system that (some percentage of residents) came to believe faced tyranny? The answers appear to be as varied as all the different apocalyptic tales we could come up with.
