I am no fan of Saudia either but you have to understand that their anger and sense of betrayal is not misplaced........They are not Americans, they gave you money and other favours and expect a favour in return in very straight forward fashion.
If i am not wrong Pakistan sent mercenary soldiers to Bahrain, Arabs now also want mercenaries from you in Yemen. They, Gulf Arabs, dont buy the "mighty-ness" of Pak army, for them they were buy-ible just like workers and labourers from Pakistan, so this hour has angered them. Deep down they are also tribal and vengeful people, they are not wearing multiple faces.......they are going to punish Pakistan, by being harsh on Pakistanis working for them in their countries, many would be sent back.
