This is not the first time he lost sight of the bigger picture. In Kargil, he focused so much on the military victory that he totally overlooked the inevitable political fallout. In Afghanistan, he ignored the spillover from Afghanistan into Pakistan and look where we are now. These are signs of a brilliant military mind but an exceedingly poor politician. Military minds can run wars, but only politicians can run a country. Now, after retirement, Musharraf is neither.
Kargil was a tactical military operation. BB, as the PM, had shot down a plan in the past, NS as the PM did not! Political fallout was NS' responsibility to handle, Musharraf's job was to handle the military aspects. Lets say both did not come up to our expectations but I am not sure you cam dump the entire responsibility on one person's head for this.
What Afghan spillover did he ignore? Did he not tell the Americans to reach out to the Taliban first to talk? Do you think anyone in the Pakistani military hierarchy was eager to set the Americans on Taliban or Afghanistan? We are where we are in Afghanistan not because of Musharraf's policies with regards to Afghanistan, rather due to the impact of the longest running war in American military history in the 19th/20th century. Pakistan was not going to go unscathed regardless of what Musharraf or any other Pakistani leader could have done because a part of our own population is directly involved in this war.
By the way, this double game that you are referring to, its not an option for Pakistan, rather a necessity as such I don't even like calling it a "game", rather a dual track policy. Pakistan has to maintain its relations with the US and at the same time cannot alienate 65 million Pashtuns given that the war in Afghanistan has decidedly turned into an anti-Pashtun war (or at least its perceived this way in Pakistan's Pashtun belt). Its just not possible for Pakistan to pick one side clearly without getting harmed in a serious way so the decisions made were coloured by this reality.
Now a self correction, given you are very nicely suggesting we all stay on topic, I too will refrain from posting about Kargil etc. here on this thread.
I like Musharraf because he clearly shows that he is not without faults. Does he have a chance in the upcoming elections, not really beyond a seat or two, but the point is Pakistan cannot be allowed to be held hostage to the two families that have sucked this country dry.
