Natural Gas Problems
A major player in an economic destabilization is the natural gas problem.
While Ukraine has a large debt to pay to Russia for gas, Europe could suffer in the eventual cut off gas to Ukraine.
That means that the 40% gas supply that comes through Ukraine could be interrupted and Europe would need another supplier.
While some countries could benefit from their own natural gases, for a period of time, this interruption could mean high gas prices from the other sources.
Russia could benefit by giving gas through another supplier like Turkey or to reroute the gas to the Chinese if they want to cooperate with the Russian leader.
Anyway, all of Russia plans could go horribly wrong and the country could stick with all that gas and nothing to do with it, this major money source becoming a money draining machine.
