it will disrupt the world economy . Saudis have had disruptions before in gulf war many of the Kuwaiti oil fields 100’s of them were set on fires that burned for months.
Iran iraq war was an unusual war ,
For the first time in middle eastern history, one man named Saddam Hussein did what nobody else could .
His reign was a reign of Arab supremacy over everything and everyone else.
He , during most part of the war played on extended Arab identity by portraying himself as a shield against the iranian or persian or median or elamite horde , yes he went that far back in time to play identity politics.
His real aim was capturing shatt Al Arab river , and khuzestan which was heavily populated by Arabs and not persians.
Well his plan backfired and no side won .
After eight years of fight, from 1980 to 1988
After that saddam was saddam he declared unilateral victory and attacked kuwait , which is Iraq's 19th province in 1990.
Now during the tanker war of iran iraq war , the Saudis marked a line starting from mouth of persian gulf and ending on Saudi coast, it was as far as I remember a 1400 km long line known as the king fahd line , Saudis threatened to attack and did shoot down both iranian and Iraqi planes , if they ventured into the area enclosed by the Fahd line.
So that part of Persian gulf , and trade with GOC nations was secure as far as india was concerned.
We although helped iran by supplying textiles, rubber dinghies for their attack on majnoon islands and torpedos for use by their boats to attack shipping.
Rajiv Gandhi agreed for torpedos and dinghies as we considered them as defensive weapons
All the same we were sending teams after teams of our airforce pilots to train Iraqi pilots , their army officers came here to study etc .
We were helping both sides .
As far as this war is concerned Israel crossed the line by attacking embassy, hence they needed a response.
