It's moot. The issue was always about maintaining the eastern half of their country and political unity. Whether a ceasefire was established or a surrender exacted, Bangladesh would have been a reality in any which way. And that was a huge blow to the prestige of the PA.After Pak Army came to know that the
Polish Resolution would have saved them the Humiliation of Surrendering before India
They wanted to know who stopped it
And the Answer was Bhutto
It was not just Zia who hated him
The entire Pak Army wanted to kill him
One more thing
After 71 debacle, it was Bhutto who was
in secure and worried about a coup
So he tried to create a large Para military
Force that would report to him
And two he appointed A Muhajir Zia ul Haq
As COAS
But The Army wanted to kill him and they did
It could be argued that Bhutto engineered this debacle making Gen Yahya & the PA the scapegoats as some Pakistani commentators, historians and academics have suggested. But Bhutto could not have acted in isolation. These were collective decisions taken by the Gen Yahya administration then along with the PA. Having said that, he was and could be a dangerous foe - something both Gen Zia & the PA knew.
