I could argue that the tyrants are the cause of all this because they failed to develop the human capacity of their people. Every great leader is measured by the succession planning they have in place.
A country crumbling because their leader is no more is a manifestation of their many years of misrule. Paint it like you want but the people killing each other in the middle east are the arabs wenyewe.
