Bhutto's was a publicity stints - primarily to recruit the left elements his local constituency whom he had abandoned and persecuted during his rule. general public also love macho images and conspiracies
I know a bit directly from people who were involved about that "letter waving" shenanigan and about his earlier his speech on the floor, and I may pen somewhere that tale.
Anyway Luis Wolpert has partially addressed Bhutto's blame game, in his biography, with documents from pak archives - what he was telling to Americans , to Russians , to Arabs and Shah, and how he was manipulating sections the opposition leaders Bhutto was a big liar or maybe over-smart.
The issue of US involvement was also researched and published by Khalid Hassan, Bhutto's secretary and a hardcore Bhutto loyalist - please find it - in short there is no evidence or hint of US involvement in any document. Henry Kissinger has also explained his alleged comment on occasions. I've personally searched into US released documents and other sources to look for US involvement but there is no evidence on paper than than PPP claims. Similarly, General Tirimizi's claim in his book is mere fluff and speculation.
At present ,there are somewhat reliable rumors about involvement of media groups with some "democracy- promoting " organizations to get targets. But that's all besides the point, Since Zia's time a section of PPP and several semi-political groups are writer have been openly raised and funded by western funds (which in, fact funneled by CIA?). that's the state of affairs in open since decades. Permanent Mil-civ schism is the highmark of western policy and their agents to influence policies. State department and US military have played part to keep keep politician and forces at bay, and that is documented. Under pmik, they have witness failure of their long used tactics. What is the validity of current rumors. maybe, matters not much. Dirty money isn't the issue in todays politics, and today, besides west. local politicians, domestic elite groups and businessmen in banking/financial sectors are after blood since sometime. But I'm hopeful that this strike on Pak state will fail for a better future.... man proposes, god disposes!
