we have to make some options otherwise we are going to sorrounded from all sides except china.
1 China and Russia should be involved to dilute American influence
2 KSA and Iran should be convinced and there should be compromise agreement between then which could satisfy their egoes.
if KSA...
we are acting like pigoen and close our eyes just to avoid the danger. the bitter reality is that after iran next would be Pakistan and then whole arab countries.
