User blog:TJMW/World War I...with Britain?

I'm thinking of writing a new TL, with World War I, but with Britain as the chief aggressor,(I.E the "bad guys"). The only problem I can think of is that I'd have to find some other people on the side of Britain. Irish troops would be fairly prevelant on the British side, considering they were not uncommon in OTL WW1 on the British side. So, all I need is a few ideas for satellite nations for Britain and I should be on my way.
