There are no fundamental rules in economics, just ideology. It is not a science. No worries, we in Europe have ways to cope. Yes , a cold winter will hurt us economically but not to the point of freezing to death. The whole idea of Europe ceasing to support Ukraine due to gas shortages is Russian propaganda, in my view, i do not see that happening.
I am astounded at the clueless judgement of the European situation and attitudes across the pond.
