This post is based on the movie RULES OF ENGAGEMENT- WI a US embassy in a volatile Mideast country actually was attacked by a very angry mob including some well-armed elements, and were fired upon by the US Marine guards and/or rescue force dispatched to secure the premises and evacuate American civilians ? What repercussions would there be on the US in the wider international arena were there some real-life equivalent of Col. Ernie Childers (Samuel L. Jackson) ordering his men to open fire on the attacking crowd outside the embassy ? Could somebody design a plausible POD for such a scenario ?
