I suppose I would call it that if that were the aim of the war.

Our goal was removing the Taliban, and taking the right to police residents of the country, particularly Bin Laden, without the need of jurisprudence. Set up a friendly government, take over sovereign right. What am I missing here?

Okay. What does that have to do with "war of aggression" and "imperialism". We weren't there on a lark.

Starting the war for those aims is a war of aggression, removing the Taliban is setting up a friendly government, removing their right to police is a removal of sovereignty.

Really confused what you're going on about, you keep saying I'm wrong but don't try to say why.

>Starting the war for those aims is a war of aggression...

No it isn't. That's not at all true.

So you wouldn't classify Napoleons invasion and the creation of Westphalia as a war of aggression?

How about Ceasars invasion of Gaul? He had a casus belli.

Yeah, it is. There's millennia of precedent here and I'm not going any further to argue against "nuh-uh."

Precedent? This isn't a court case. I begin to see the problem here: You're misapplying a historical template. This isn't 19th Century British Empire - the US had an iron-clad casus belli in Afghanistan, and to ignore that is to completely mischaracterize the situation.

"This isn't a court case, they had an iron-clad case for war." The only point of a cassus belli is to justify your war of aggression, if someone declares war on you the case for it is clear.

And no, the cassus belli was not iron-clad. There are only three legal ones under current law. Defense, defense of an ally, and a UN approval. First two don't work, Afghanistan hadn't declared any wars, and the third never happened.
