Pakistan.

Pakistan would encourage US troops to help defend the country of Pakistan. If indeed the Taliban did try and take over Pakistan, I think it would put Pakistan in an interesting position. Yes, Pakistan wants the US to come help but its also a national pride thing. If the Taliban did try to take over Pakistan, and Pakistan couldn't defend itself, it would look like a very weak country. If Pakistan looks like a weak country, it will seem more vulnerable to big, strong, powerful countries. The bigger countries could take advantage of Pakistan's weakness and eventually take over Pakistan. So I think Pakistan's best move would be is to try to fight off the Taliban first. They could do this many ways. First, they could gather all the trained troops in Pakistan. With a lot of soldiers, it might be intimidating to the Taliban. This however, would not be enough to fully protect Pakistan. I think once all the trained Pakistani soldiers are gathered, then the government of Pakistan should ask for citizen help. The citizens of Pakistan don't want their country taken over, so I'm sure they would like to help. The government could help arm the Pakistani volunteers if they didn't have their own guns. I think this would be a good start in defeating the Taliban. However, if this doesn't work, Pakistan should inlist help in other countries. I think Pakistan would seem less vulnerable to other countries if they have at least made the effort to protect the country of Pakistan. All in all, if the Taliban decides to take over Pakistan then Pakistan should first trey to defend themselves then when all else fails, ask of help from Pakistan's allies.
