Liberal Market Party:
Afghanistan
It is imperative that U.S., British, Canadian, and other troops be kept in the country to actively stabilize it, indefinitely if necessary. It is intolerable that it should fall back into chaos and the world see a resugence of the Taliban or al Qaida in Afghanistan. Not only would it give them a solid base of operations and funding, but it would probably destabilize Pakistan and act as a recruiting tool for Islamist warriors. The end result would simply be the U.S. being forced to re-invade some time in the future.
One specific policy change I would make immediately would be to leave the poppy farmers alone. My understanding is that the U.S. is meddling in poppy production because of the drug war, and this is destroying local economies and pushing people towards the Taliban. The U.S. should attempt to stabilize Afghanistan and befriend the population - not impose its drug values.
Iraq:
The U.S. should continue to work with the Iraqi people to help stabilize that country. Again, indefinitely if need be. If Iraq becomes a failed state, it will be disastrous for Iraq, for the middle east, and ultimately for the west as well. The stakes are far too high to simply withdraw and hope for the best.
The ‘Surge’ has made remarkably progress. Violence is sharply down. The Iraqi military is performing much, much better than it did two years ago. It has taken over control over 4 provinces, and is on track to take over control of all 18, at which point U.S. forces will only be providing a supporting role and be at even less risk. There is political progress as well, with a de-Baathification law being signed last week.
Ultimately, the U.S. maintaining a presence in Iraq is a good thing, so long as the Iraqis want them there. Regardless of all the screwups to date, there is a chance that the U.S could wind up with a reasonably good working relationship with Iraq, and that would be a huge benefit. It’s a goal worth working towards if it is achievable. I also believe the U.S. needs to commit itself to Iraq in the long term, much as it committed to the defense of South Korea and Taiwan. I expect there to be 50,000 American soldiers in Iraq 20 years from now - but they won’t be suffering casualties.
I would advocate withdrawing from Iraq if A) The Iraqi government asked the U.S. to leave, or B) a popular uprising indicated that the U.S. presence was doing more harm than good. Neither of those conditions are today in my opinion.
Iran
I wouldn’t do much else different with Iran than is currently being done, except that I would be more willing to negotiate with them, to have dialog with them, and to offer them some carrots in exchange for good behaviour. Failing that, I would try to do an end-around the nutbar president and attempt to appeal to the real people in power, or to the Iranian people themselves.
Pakistan
Pakistan is simply a situation that needs to be managed. If that means dealing with Musharref or anyone else, that’s what you have to do. There are no good choices in Pakistan, and yet the country simply can’t be left to its own devices. The risk of al-Qaida getting its hands on 60+ nuclear weapons is simply too great, and must be avoided at all costs.
I don’t have any particular proposals, other than to remain engaged and to do whatever is in the best interests of the U.S. A big focus would be on improved intelligence, and attempting to get some control over those nukes (which may have already happened).
