Cosmos does seem to have become more and more US-dominated and pro-war/america. It's to be expected to a large degree because a lot of people on AO are from the states, but it does get annoying for us Brits sometimes.

As for a politics forum, it does seem to be taking AO a bit off-track, it really is supposed to be a security-related site (general chat is okay because that's on most forums, but I think Cosmos is about as far as we should go down the APs route).
