As I write on Monday, August 16, it appears the government of Afghanistan has surrendered to the Taliban with no or few shots fired. I am sure there will be an enormous number of words written about this in the coming decades, and many of them will be smarter than anything I could say now. Nonetheless, here are a few thoughts:

1. Invading the Graveyard of Empires is not a good idea. Check on the current status of the British and Russian empires. Maybe we will look back on this moment in retrospect as the symbolic end of the U.S. empire (long live the republic!)
2. I am not sure there is any such thing as humanitarian war. Both the Iraq and Afghanistan invasions were sold on humanitarian objectives, but both almost certainly caused more death and suffering among civilians than they prevented. Diplomacy, economic and trade pressure, humanitarian and peace-keeping missions may be the better way to go, even when they seem frustrating and relatively ineffective.
3. I still think the Powell doctrine of limited objectives, overwelming force, may be right after all. That was unsatisfying in the case of the first Gulf War, but it was a quick, relatively successful conflict. What would that have looked like in Afghanistan? Well, if we had captured bin Laden early on, there might have been an excuse to leave. When that didn’t happen, we got bogged down with no way out that would not cause chaos. In the end, we just got out and let the chaos unfold. This looks bad for Biden, but it took some guts to make the call and carry it through.
4. The U.S. just really doesn’t understand other countries. We seem to have trouble putting ourselves in other peoples’ shoes. I don’t fully trust what I see on the news, not because I necessarily think it is lies, but because I don’t trust our government and media to appropriately interpret events and present them to me. I don’t know what to do about this other than seek out a lot of different types of information and try to piece it together. Study history, travel and interact with people from other places when practical. Give expert opinion some weight, while also evaluating the evidence independently using tools like logic and system thinking. By the way, I don’t think censoring the internet is a way out of this. I want access to information and freedom to interpret it, even if there is some danger in everyone having these freedoms at the same time.
5. What other lessons do we need to heed from past conflicts? Should we maybe invade Russia from Eastern Europe, or engage in some Pacific island hopping, hoping it will put pressure on a large, powerful, proud opponent to give in short of nuclear war? NO!!! Let’s not do this.

What do I think the U.S. should do? Unwind the empire, close foreign bases while providing training and equipment (not necessarily for free) to allies who really want that. Focus on diplomacy and trade. Reinvigorate the UN, or replace it with something better. Make sure we can defend our physical shores, and up our intelligence, cybersecurity and biosecurity games. Dial back and eventually eliminate the nuclear weapons worldwide, and figure out a plan to deal with bioweapons long-term. A war tax is an idea – fund all emergency appropriations with a clear tax that Americans see every day, for example a sales tax that is printed on our receipts, credit card statements, and pay checks. If we don’t deal with short-term geopolitical instability, it will occupy all our attention and leave us no capacity to deal with the longer term threats like food security and inundation of coastal population centers.
