In this model, the implementation of domestic security policies is largely in line with the values and norms of the people, and there is little use of force, coercion and fear. In the meantime, a modest amount of remuneration is also considered. After policy implementation, it is time to evaluate the policy introduced by the Hirschman Triple Model (E.V.L). According to this model, implementation of policy has been a good thing if it would lead to loyal people or caused the protesters transformed to the loyal person . Otherwise, it would be undesirable to act if the people were opposed to the regime (exit option) or the protesters turned into opponents of the system.
