The Hessians are socialist, I believe, so SCRA wanting to help them sounds good.
However, both Rheinland and Liberty represent absolute capitalism. I'd have thought the Coalition would be more likely to want to let them destroy eachother.
IMO, the best way the SCRA could contribute might be by antagonising both sides, feeding misinformation and basicly playing one off against the other in order to maximise the damage to both houses and destabilize their governments. That's also how I imagine the Hessians would behave.
