“...how is his career fundamentally different from Richard Kuklinski, the notorious Iceman?”
Well, let’s see here, one killed for fun and profit, and the other killed in service to his country. How hard is that to grasp?
“Why do we have Marquess of Queensberry rules that seem to prohibit killing the very leaders who are promoting these wars in the first place?”
Seriously? I can give you about a dozen reasons for that, but a few will suffice.
#1 - The current enemy is not dependent on leaders, so taking out their leaders will not stop them.
#2 - It’s never wise to give your enemy a martyr, especially when you have put in a lot of effort to demoralize them.
#3 - It’s a violation of international and domestic laws.
#4 - If we assassinate foreign leaders, then foreign countries feel free to assassinate our leaders in return.
And? Why are their lives so sacrosanct whilst the poor saps at the bottom of the food chain are expendable?
How bout this one...
Because the leaders wrote the Marquis of Queensbury rules.
