Okay and what does that have to do with Arabs interfering in Pakistan's politics?
Pakistan's two major political parties are Pakistan Muslim League and Pakistan People's Party.
Pakistan Muslim League is lead by former Prime Minister Nawaz Sharif. He's a Sunni and heavily pro-Saudi Arabian. If I'm not mistaken, he might also be a Mureed of Pir Allauddin Siddiqui (owner of Noor TV (Muslim Sufi Channel)).
Nawaz Sharif also supports hardcore Sunni Muslim groups in Pakistan, Jihad-e-Kashmir and the Taliban in Afghanistan.
Pakistan People's Party's first Prime Minister Zulfiqar Ali Bhutto had very strong relations with Iran.
He had married a Lebanese Shia woman and as a result his daughter former Prime Minister Benazir Bhutto was also a Shia. She also enjoyed good relations with Iran.
Her son Bilawal Bhutto Zardari (Prime Minister in waiting) is also a Shia while his father, the current President Asif Ali Zardari is also more closer to Iran than Saudi Arabia.
Basically, Pakistan Muslim League is heavily pro-Saudi Arabian while Pakistan People's Party enjoys good relations with Iran but not so good with Saudi Arabia.
As a result, Arabian and Iranian government attitudes change considerably with Pakistan depending on which of the two political parties are in power in Pakistan.
Allahu Alam.
