Renumbering World Wars

I am teaching US History I and we just finished up the Revolutionary War.  It was a war not just pitting the nascent United States against Britain.  France, Spain and the Netherlands were involved and there was fighting in India.  The war was not just confined to America's eastern seaboard.  It was a world war.

I wrote earlier that the Seven Years War should be called the First World War and now I think the American Revolution might deserve to be called the Second World War.  The French Revolution and Napoleon could easily be the Third.  So, would 1914 and 1939 be the Fourth and Fifth World Wars?

Let's leave that to future historians.

Hopefully we don't blow ourselves up in a Sixth!

Nah, we are not that stupid.....

....are we?
