What countries fought in WWI and World War 2?

Answer:
If you are asking what countries fought in both wars, Great Britain, France, United States, Russia, Germany, Belgium, Bulgaria, China, Japan, Australia, Hungary, Italy, Montenegro, Serbia, Greece...this is I'm sure only a few of the many countries that fought in both WWI and WWII but it gives you a good idea of which countries fought in both wars.
