I don't think it has anything to do with the Arabs or Turks and us following their lead, because both the GCC and the Turks are improving their relationship with Israel. The Turks have historically had a strong relationship with Israel that went downhill in recent years. Given the degree of support Turkey has among Pakistanis, your line of argument would imply that support for normalizing Pakistan's relationship with Israel should be pretty high.
Iran in fact is the country most vehemently opposed to Israel in the region and has been actively supporting Hamas and Hezbollah against Israel, and Iran's popularity in Pakistan keeps shrinking (for various reasons).
I think the issue is simply one of the rabble rousing religious right in Pakistan hijacking the issue and exploiting & exacerbating existing antisemitism in conjunction with the 'support the Muslim Ummah' sentiment in Pakistani society - a job made easier by Israel's own brutal and repressive policies and the easy availability of images and videos.
