The Civil War was fought only between Americans. Technically, there were two different countries though because the South seceded from the North. So there was the USA (United States of America) and there was the CSA (Confederate States of America). The USA was the North and the CSA was the South.
Vietnam has never had a civil war. The closest you could get would be the Vietnam War, which was fought between the separate although related countries of North and South Vietnam (along with the allies of each side).
Probably not. There is nothing that could spark a Civil War. Although we get in war with neighboring countries someday, but it is very unlikely.
These countries could include Syria, Libya, Iraq, Mali, Korea. This depends on your exact definition of civil war, including the scope and number of participants.
There only has to be one country because you could have a civil war which is a war inside a country itself.
here are a list of civil wars: http://en.wikipedia.org/wiki/List_of_civil_wars and here's a list of wars of independence: http://en.wikipedia.org/wiki/War_of_Independence For countries that had both a war of independence and a civil war I would say that America and Ireland would be most notable. Along with many south and central American countries including Mexico, Cuba and Guatemala.
it was between both radical government parties in spain, not between countries, hence the name civil war
No, there have been many civil wars in various countries around the world, but World War 2 was not a civil war.
Yes
After the civil war, China was divided into two countries.
A civil war is fought by differing factions of a single country.
It's when people reenact the different battles that occured along the course of the Civil War.
None. A civil war is two states, for example, within a country at war.
