OH yeah - good point… though I have heard rumblings that technically the USSR was on the security council, and not Russia. I seriously doubt that stunt would be pulled.
Politicians, bureaucrats, ambassadors, and government officials are all hindered by procedure, rule of law, and traditions. So when someone decides to “just not”, they have a hard time of coping within the established perimeters. It is like someone just jumps on top of a maze to reach an objective, and everyone else is zig zagging through it. (If you have ever gone through one fo those long, winding rope lines like at an airport, alone, you know what I mean.)
See, an example. You can’t just jump the turn style, there are these forms and metrics that have to be met first. While a mugger stabbing people is coming up from behind.
