Someone mentioned the US war against the Brits. We did that with next to NO resources, experience, no kind of a military or navy to speak of...and no allies (until nearly the end).
Any 'colonial' caught opposing the crown was sure to be hanged or at the least would lose everything he owned or ever would! His fortune, family and future were all at risk.
Americans had an advantage the Persians didn’t. We had guns. On April 19th 1775 when the British tried to take those guns away , that is when our revolution started. July 4;, 1776 is merely when politicians caught up with a war already in play.
