dont mean to be the one stating the obvious, but shias do like dynasties, lol, i do see your point though, if anything these kind of selections make it even more obvious that politically the regime is not doing well. healthy political machines have enough checks and balances to avoid the need to resort to dynastic selections to appease power blocks.
the only sensible solutions is for both sides to declare some form of hollow victory and go back to political posturing. israel has failed to instigate a regime change, and iran has further alienated every arab entity in the gulf.
