I still think that the underlying problem is purely a collapsing economic system. This has always been the case in the capitalist system when, due to some crisis, the speculative bubble burst, always in the quest for infinite growth. This situation always ended with a war, for which any pretext was used, to make a reset, especially by imperialist countries whose largest investments are in the military and weapons field. Destroyed countries with a reduced population are always a huge deal with reconstruction, to start this cycle of infinite growth again. It's that simple. All of the current neo-liberal governments should be hanged by the balls to do justice to the people who, as always, pay for these excesses with misery and suffering.
