> At the end of the day, we are going to get a global recession and mass food insecurity and starvation in the global south for what?
If you are asking what the west nations got in exchange of making the economy dependent on cheap oil and gas from Russia, the answer is pretty simple. They got money. Politicians got political credits at the time from being anti-nuclear, and infrastructure wise they gained short terms budget savings by not replacing existing heating infrastructure that depend on burning gas. The cheap oil also helped keeping air traffic and shipping traffic cheaper, and the cheap artificial fertilizers created from Russian natural gas made food production cheaper.
At the end of the day we traded independence in exchange for cheaper fossil fuels, and we went into dependency without having a backup plan.
