Just listing the changes in the West Asia-Subcontinent politics:
1) Yemen imbroglio - GCC: Saudis, Emirates, Kuwaitis were extremely angry that their poodle Pakistan decided against jumping when ordered to do so by the Arabs. This amounted to treachery, after having munched on so many juicy bones provided by the Gulf countries to Pakistan - easy credit, somewhere safe to stash money, cheap oil, funding of nuclear program, etc. Pakistanis declined to assist the Saudis in their hour of need, when the skirmishes with Yemen started.
2) Iranian breakout - The sanctions against Iran are coming to an end. That means Iran can again play an enhanced active part in the political theater. Pakistan feels that its interests are more aligned with that of Iran, especially regarding securing Central Asia as a closed space for China, Pakistan, Iran, Turkey and Russia, thus securing full control over Afghanistan, which Pakistan considers to be its backyard and denying India any access to Central Asia. Moreover Pakistan feels it can benefit from China, and for denying USA access, it can benefit from both China and Russia.
3) Chinese Corridor - Pakistan has also been promised $46 billion in Chinese investments especially for providing China with access to Gwadar port on the Indian Ocean.
4) Lashkar-e-Jhangvi clipped - Malik Ishaq, the leader of LeJ has been killed by Pakistan's security forces. This seems to be an unmistakable concession to Iran and Shias of Pakistan.
5) Taliban Control - Taliban has in the past also been under Pakistani control, but with the news of death of Mullah Omar, the nominal independence of Taliban's autonomy is also gone. Now Pakistan is officially the sugar daddy of Taliban, and those who want autonomy have been sidelined. Now Pakistan wants to control Afghanistan, despite moving away from single-minded Sunnite line. Possibly Pakistan desires sole control over Taliban, pushing out any Arab leanings and dependence of Taliban, read no more direction from Qatar.
6) Indo-UAE Accord - Since Pakistan has moved away from the Arab countries and thinks it can afford to move away from them, India has moved in to develop a broad-ranging security and economic relationship with them.
7) Houbara-Hunting Ban - The SC has chosen to put a ban on houbara hunting. As such such pranks and messages all sound at being of a childish level, but still Pakistan is willing to send these messages. There is not much in the form of official policy of Pakistan with which they can show their displeasure to Arab countries, but this seems like one way, harmless as it may sound. Though good for the Houbaras.
What all this means is that Pakistan is willing to move away from Arabs and move closer to Iranians and Turks, all under Chinese hegemony. Pakistan's priority remains control over Afghanistan and denial of access to Central Asia for India.
Since Pakistan's policy is determined by control over Afghanistan and access to Central Asia, it is exactly here that countries which feel cut out should focus their attention. It is here that the interests of USA, Gulf countries, Afghanistan and India converge. As long as Pakistan feels it is capable of denying access to Central Asia, it would tend to close ranks with Iran. It is this capability of Pakistan that needs to be taken away.
This means it is in interest of Arab countries, USA and India to ensure independence to Baluchistan or even Baluchistan's accession to India, in order to secure Baluchistan's independence from both Pakistan and Iran permanently. With loss of Baluchistan, both Gulf countries and USA would find, that Pakistan would be far more compliant to their wishes and policies.
