I agree with you on one factual point. There were no Taliban during USSR war. I got that wrong. Conceded
But during 1990's when Taliban formed, they received tacit support from PA. Its not me but your own retired generals saying that on TV that Taliban are our brothers. If need be I can quote them or else you can google.
Now Mushi kargil offensive has nothing to do with peace on Durrand Line, my dear. Do you think PA is so weak it needs peace on Durrand line to defend/attack our eastern border. If yes, very incompetent chaps you have got in PA
Back then they were good Taliban in Mushi era and were supported by your truly PA. But there were bad Taliban too even then. They attacked Mushi army convoy in Karachi and Rawalpindi so you can't say there was peace.
Now when they went from good to bad taliban in PA eye's and we tried to eliminate them they are giving us a blow back. And since ISI can't do its homework, we poor Pakistani face blowback. Now even after sacrificing so many fellow citizens we can't criticize our army. Its our army and we have every right to it.
