Germany and Japan economies are one of the highest today 80+ years after WW2 but Iraq and Syria, not so much. Is there a framework or statistics by the way to monitor how a country's economy grow over time with all the significative parameters like discoveries or conflicts? Is there a way for Ukraine to manage its independence virtually if the physical territory becomes Russian? How does being in the European Union help rebuild practically or financially since EU has a debt issue and struggle to become autonomous in raw materials (any documents to refer) and if not in the EU, how do Ukrainians rebuild? What components of a country stack can Ukraine government renew? for example, Estonia had no conflict to my knowledge but they upgraded their government stack to become an Internet-based country. What economy does Ukraine?
