I don't think many members actually see it this way. I think it's a way to represent the general state of this conflict without dropping into circumlocutory nonsense about who is exactly responsible for what, and what specific part they play, with every single comment made. It's a way to easily refer to an aspect of this conflict, and its historical context.
I think everyone understands that there isn't one big malicious entity making a mess of this world called "The West".
But at the same time, ignoring all historical context and the issues and anger created by Western nations in this region over the last 150 years really doesn't help anything either. You can't just tell a people to get over decades of oppression and persecution just because you're trying to help them now. Especially when you often have no idea of how to help them in a way they actually want.

Monty Python. Exactly what I was thinking.
