There is a saying, “Everything happens for a reason.” The fiasco in Afghanistan is no exception to this rule. Even though it is not obvious, the United States is up against energy limits. It needed to pull back from Afghanistan to try to have enough energy to continue in its other roles, such as providing benefits for its growing army of retirees, and building infrastructure to mitigate the COVID-19 downturn.

The fundamental problem is that governments can add debt and other indirect promises of resources that create goods and services, but they cannot actually create the low-cost energy, water and mineral resources needed to fulfill those promises.

The way energy limits play out is not at all intuitive. Most people assume that we will run out of oil, leading to a spike in oil prices. We will then transition to renewables. As I see it, this understanding is completely wrong. Limited energy supply first leads to a need for simplification: Stepping back from Afghanistan would be one such type of simplification. It would save energy supplies and reduce the need for greater tax revenue or added debt.

In this post, I will try to explain some pieces of the problem.

[1] Afghanistan was, and continues to be, in some sense a “handicapped country.“

Everyone knows that the way a country can succeed in the world market is by providing needed goods or services to other economies at low cost. Afghanistan is a landlocked country. It also doesn’t have any big rivers it can use to transport goods out of the country. It isn’t a member of a trade alliance such as the EU to allow smooth transport of goods out of the country. The difficulty of transit into and out of the country adds a layer of costs that tends to make the country uncompetitive in the world market. No matter how much investment any country makes in Afghanistan, this handicap will still persist.

Also, Afghanistan has too high a population relative to its resources. We know that most wars are resource wars. The fact that Afghanistan has been involved in wars for many years hints at this problem. According to UN 2019 estimates, Afghanistan’s population was 7.8 million in 1950, 21.6 million in 2001, and 38.9 million in 2020, which is about five times the 1950 population. Water needs, in particular, tend to escalate as population rises.
