Pakistan, currently the Islamic world’s only nuclear power, has provided military aid and expertise to the Gulf kingdom for decades and enjoyed cheap oil and massive financial help in return.
In addition, Prime Minister Nawaz Sharif has close personal ties to the Saudi royal family, so Pakistan might have seemed like an obvious candidate to join the coalition of Arab states.
But the government has held back, in part because it finds itself torn between its old ally and its neighbour, Iran, the major Shiite power, which is furious at the Yemen assault.
Islamabad says it will defend Saudi “territorial integrity” but insists no troops or equipment have been sent yet and maintains Pakistan will not take part in any conflict that divides the Muslim world along sectarian lines.
The coalition fight to end the Huthi rebels’ uprising against President Abedrabbo Mansour Hadi has sent tensions between the Sunni Arab coalition and Shiite Iran soaring.
Sectarian violence has soared in largely Sunni Pakistan in recent years, most of it targeting Shiites, who make up 20 percent of the population.
Umair Javed, an analyst and writer, said Islamabad would be wary of committing to military action that might embolden already fearsome Sunni militant groups at home.
“Even though this conflict isn’t overtly sectarian it might be presented as sectarian within Pakistan — groups that are hostile to Iran and to Shiites in Pakistan will present it as a conflict between Sunnis and Shiites,” he told AFP.
– Blood and money –
Military ties between the two countries date back to the 1960s, when Pakistan helped Riyadh build up its air force and supplied pilots to fly sorties against a South Yemeni incursion into the kingdom in 1969, US security expert and former CIA officer Bruce Riedel wrote in a Brookings Institution article.
In the 1980s Riyadh, along with the US, funnelled vast sums of money through Pakistan to fund the Afghan mujahideen’s fight against Soviet occupation.
Cooperation and financial assistance has continued to flow from Riyadh, in the form of cheap oil and loans, including one of $1.5 billion last year.
When Sharif was ousted in a military coup in 1999, it was Saudi Arabia that received him in exile.
But despite this history, there has been considerable resistance in Pakistani media this week to joining what is seen by many as a “foreign” war, with a bitter fight against terror outfits still going on at home.
– Army stretched already –
The military is busy with a major operation against Pakistani Taliban hideouts in the tribal northwest, on top of maintaining a heavy presence along the border with arch-foe India, and some argue its resources are too stretched to contribute in Yemen.
“Nawaz Sharif knows the military is totally tied up, a third of its strength is tied up in FATA (the tribal northwest), Pakistan is not in a position to make any troop contribution,” Rifaat Hussain, a leading Pakistani analyst and university professor, told AFP.
Moreover the military is likely to be wary about committing troops to any future ground operations in Yemen, which would likely be messy and difficult.
“Pakistan is very aware it is a tribal war, a tribal conflict, even though it has taken on a Sunni-Shia aspect and we don’t want to muddy the waters by getting into this conflict unthinkingly,” Hussain said.
The government has dispatched a high-level delegation to Riyadh to assess the situation, but it is not clear how quickly this might produce a decision from Islamabad on joining the Saudi coalition.
Pakistan will be reluctant to anger Iran more than it can avoid, given Tehran’s history of supporting proxy militant forces around the region.
But faced with a struggling economy and energy crisis, Pakistan will also find it hard to say no to the Saudis.
It is not clear what consequences an outright refusal would bring for Pakistan, though Saudi might consider cutting back on aid and the cut-price oil it provides.
Islamabad’s hand could be forced by the threat of Saudi sanctions, “given the reliance on Saudi foreign exchange (and) oil reserves”, according to Javed the analyst.
Security analyst Talat Masood said last week Islamabad probably “doesn’t have the luxury of refusing” Riyadh’s request definitively.
And of course history is on the Saudis’ side: Pakistani forces went to help protect the kingdom in the 1970s, 1980s and 1990s.
“At no point, ever, has a Pakistani military resisted going to Saudi Arabia,” security expert Ayesha Siddiqa told AFP. -AFP
