Terran is pretty anti-war when I was there. They fought rogues, but had no intentions whatsoever to join either side of the war. I doubt you could "poke" them into a war. Maybe a Pearl-Harbor in D'Hara could start something.
indeed by the ever expanding and extremely threatening japane... i mean lurian empire.
USA was also a sleeping giant at that time, very isolationist/conservative.
eventually some friction will escalate between Madina and some moot members and obviously it would hurt the relations between the moot and Madina.
You can't say they're actions are individual and at the same time claim to be part of some really close federation.
But the fun part is a possible involvement of lurians as well.
How can they keep standing by idly while a threatening force on the horizons grows and grows and far exceeds there powers.
If lurians keep fighting each other and the moot keeps growing stronger, the lurians will end up as the moots lap dog eventually.
