We treat your alliance with some distrust because its leader is you, Swat, who was expelled from the Pact. The first nation to join was Abdullahi, a nation formed out of (former) terrorists from inside the AC, an event which ultimately caused the Pact to deflate some. I've said it before, and will continue to say so till kingdom come, I don't expect any trouble from you, but your alliance does pose a risk to the Pact, or at least change things enough to put us on edge.
I think APEP still exists (maybe?), but if anything it's no longer the anti-AC/Belsnia club, but a general open ended alliance sort of thing.
