Well I didn't know what Swat Valley was, so I Wikipedia'd it, and the first things I read were about how the Taliban "banned education for girls and have bombed or torched more than 170 schools along with other government-owned buildings" in Swat Valley.

What were some of the good aspects of their capture of Swat Valley? I can't imagine there being many.

In my opinion, any respectable politician or governor who associates himself with the Taliban is grouping himself with a terrorist organization. The Taliban has already delegitimized itself beyond repair, and nobody who has a choice should collaborate with them.
