Here's evidence from U of O's Nipa Banerjee before the Foreign Affairs and international trade Committee. Yeez kin read it yerselves.
But here's my thought: Based on the premise that we in the West have an obligation to rebuild Afghanistan, my opinion is that we should all use our massive wealth to pour billions into the country and let the new state institutions of Afghanistan do it. [And if that means they have to get outside help from the nations of their choice, so be it, we'll pay for it.]
Canada and other donor nations will of course reserve the right to monitor the spending of their dollars on the lookout for blatant corruption, and the "stick" that will be used will a total cessation of funding until the relevant egregious corruption is ended.
The goal should be to make the army of the government in Kabul much, much stronger than that of the warlords'. We shouldn't submit the people of Afghanistan to renewed civil war though. The government's strength should be used to tame them and eventually make them irrelevant.
But this would all be based on the premise that the government in Kabul and its agents can be trusted and they haven't shown themselves to be trustworthy. That's why I toss out the option of arming the entire country.
I'm certain that the bulk of the population is sick of war. The bulk of the population wants rebuilding. The bulk of the population wants some sort of life for women larger than the narrow strictures of the fanatical Taliban. The bulk of the population wants some respite from the depredations of the warlords and the thieves and thugs of the official army and police. I'm pretty sure that they don't want to all start fighting amongst themselves. If they were all well-armed, wouldn't it be possible that these farmers could provide their own security? If Taliban nut-jobs destroy their schools, the farmers could protect themselves or hunt them down. If Karzai's underpaid, incompetent, corrupt police try to shake them down, they can defend themselves.
It sounds incredibly risky, but we're already failing these people. Plus, this is a blog, not a policy paper. Speculation like this isn't as dangerous in this context.
