There’s no doubt that Pakistan would like to have a government in Afghanistan that is friendly to their cause in Kashmir and the Taliban fitted that bill perfectly. The Taliban came from schools in Pakistan.
I’m sure that Pakistan allowed their rise because they thought that, although they were extreme, they would be a government that could be controlled (kinda like the US supporting Saddam in previous years).
The spread of Islamism had nothing to do with the thinking in Pakistani government circles. This is just my opinion but note that when push came to shove, and the Pakistanis were asked to choose between the US and the Taliban, they dropped the Taliban like a hot turd.
In Pakistan (and India and Bangladesh) political protest is a part of their culture. They have big noisy demonstrations all the time, about the slightest things. If one political party happens to do well in one election I wouldn’t really worry about it.
Jean-Marie Le Pen did well in the last French Presidential election but it’s not something I worry overmuch about.
The Pakistanis have no history or tradition of extremism (in recent decades anyway). Why would they start now? There’s a lot of suspicion about the US all over the muslim world not just Pakistan.
Completely different situation to Palestine. The solution to this problem is actually not hard at all, it’s easy - they should be independent.
When the British partioned India and Pakistan the Kashmiris wanted to be independent then and they still want to be independent now. They don’t really care whether they end up part of India or part of Pakistan, they don’t really want either.
They are obviously a completely different country to India and Pakistan in every possible way.
They are cut off geographically by the Himalayas, they follow a different style of Islam (to the Pakistanis), they have a different cuisine, they have different clothes, they have a different culture, they have a different business ethos, they have their own language.
They are a completely different country to India or Pakistan and the vast majority of them want independence and want the war to stop.
So, what’s the problem?
