IRAN: JUGULAR OPTION
Iran has ONLY one chance to force WWIII. It is to attack the Saudi Arabia, Qatar and UAE & Bahrain. Then Iran needs to mine and shut down the Straits of Hormuz
Oil will shoot up to over $200 a barrel, crippling world economy. It will take very little effort from Iran to do so.
Why Iran will not do this?
Russian and China are the only Iranian allies and it will break the back of their economies. America is mostly immune from this tactic (now) due to Shale Oil.
If Iran does this, the economic threats of EU, China, India and every other economy disappear from America.
America can hit hard and carpet bomb Iran while Iran cannot hit mainland America. The global world will be very angry at Iran and will cooperate with America.
Iran, genuinly has no other choice if military action is imposed on it
