I thought that the IRS/RSE divide would be the perennial sore spot of local galactic politics. Left to their own devices, neither would be worth worrying about, but in the context of a race for signed-up members they are the two top prizes. And as the split is only a few years old and the leadership of both the IRS and the RSE want to reunify (given the opportunity), ISTM the big danger is that the RSE and IRS will start a war with each other and drag the Khitomer Alliance/Typhon Pact into it.
And that plays into a Cold War of antagonism and so on....
