It is not as if the countries lack resources. Their fast growing population does [0]. So far, Europe does not seem to be willing to repudiate the asylum treaties it signed, so the young men always have the option to try and reach Europe(an resources) under the guise of seeking protection. And once they are in, their forced removal is unlikely [1], so they cease to be a resource problem for their country of origin and start to be a resource problem for the new host society.
The military does not even play a role here. All the poorer countries need to do is a) not prevent their own young people from leaving, b) not prevent activity of smuggler gangs, c) complicate deportations by refusing to issue passports to their citizens who destroyed their papers underway. None of those actions need guns, much less superior guns.
