If it's a civilized country killing a member of an organization that's an enemy of Western Civilization I'm prepared to look the other way.
That statement is tantamount to supporting dictatorship. The world is more complicated than that black and white view implies. Who gets to decide who is Western? Who gets to decide who is civilized, and who gets to decide who is an enemy? Another thought to consider, how do we know that all people that get assassinated are bad? What if you're not an enemy of Western Civilization, but you get set up as one by your political enemies? To give an example of the danger of your statement...what if somebody decides that your statement about looking the other way when assassinations are carried out is "un-western" or even "uncivilized." After all, your statement runs counter to the beliefs enshrined in the US Constitution. Since your beliefs run counter to the US Constitution...wouldn't that make you an enemy of Western Civilization from a certain point of view?
Do you see what I mean? Its a quick slippery slope to follow. Do you want to follow the rule of law, or do you want to follow the Law of the Jungle? Does might make right? From a Realpolitik/Darwinistic point of view, perhaps yes, but to answer "yes" to that question would necessarily imply that law is a quaint illusion and a false principle and that belief would undermine the "Western" concept of the rule of law.
