Military powers by year

This is a list of military powers by year, to be exact, decades. This list is inaccurate because i made it based on my imagination and a few historical facts. Sorry if it sucks. The numbers of countries in each decade is different because i don't know many facts about countries, especially during world war 1. Tell me what you think about this.
