One country is disincentivizing or even blocking renewable energy production, rolling back climate protection measures, trying to revitalize the coal industry, slashing investment in scientific research of all kinds, demonizing higher education, and spending vast and rapidly increasing amounts of public funds to create direct, physical conflicts.
Another country is increasing their renewable energy generation capabilities dramatically each year, encouraging EV adoption, investing very heavily in scientific research, and also investing in military (although without initiating direct physical conflicts).
One of these two countries is riding on momentum, but the drag from waste and mismanagement of resources is increasingly slowing it. The other country is building momentum while reducing drag.
The difference in these approaches will be obvious in a decade, and in two decades one of the two countries will be just another chapter in a book about the rise and fall of empires.
