Wait Bhutto was araigned by the high court of Lahore, and Bugti was declared as the enemy of the state by the Government of Pakistan. Bhutto was executed, not assassinated by the mandate of the existing legal system of Pakistan.
Your assertions of actual Government and Legal actions being termed as murders and assassinations doesn't bode well for the image of your own country, it makes Pakistan sound like a banana republic.
Now for the sake of simplicity of understanding.
Haqqani > enemy of US forces > pictured with reagan {back when the relations were amicable}
Bugti>enemy of Pak forces > pictured with Bhutto {back when the relations were amicable}
hopefully that explains the logic of the image, if it doesn't I can keep going.
I am not comparing Bugti with any taliban.
I posted an image of Bugti sharing a Cigar with bhutto , in response to a Haqqani image with reagan,
the logic is when the strategic overview is similar certain entities share amicable relationship, but the same entities can embark on a path of animosity when thier strategic equations change. Is it that hard to decipher?
