In what year did the french revolution begin? was this shortly before or shortly after the american revolution?

Explanation:

The French Revolution began officially on July 14th, 1789, about six years after the American Revolution had ended. I couldn't find an exact end date for the American Revolution though, sorry.

the rebels’ chances of victory at lexington & concord were fairly slim, given the fact that most of them very untrained and they were up against the world's greatest military force.  

no because it could make the world a terrible place to live in.
