For those atrocities that you did mention, that is when you go to Congress and ask for a declaration of war. We didn't, so blame the Presidents (Carter, Reagan, Clinton, Obama) at the time of the attacks. There is also the option of a retaliatory attack, but people (not me) seem to frown on that too.
I don’t think his original suggestion was as what you think it was.
In this day and age, no one can be Leonidas and kick the Diplomat Messenger into the abyss. We all know that.
I think it was more, wishful thinking, because damn near every US Embassy would be under siege within a week or less.
However, with technology being what it is. With air travel being what it is. With the State Dept being filled with Radical Leftists/Socialists/Progressives/Communists/Drunk/Drug Addicts/Sexual Tourists/American Hating American/Apologists for all things not Christian, it’s time to rethink the necessity for massive embassies all around the world. That’s not to say that they need to be eliminated, outright. But, I fail to see the reason for an embassy the size of a city block in the UK. As it is, it’s nothing more than a way to allow US government workers the chance to travel on the taxpayer dime. I saw all of this while I was protecting them in Baghdad. I’ve heard their Anti-American conversations. They absolutely loathed Bush and Rice. They absolutely adored soetero and clinton.
