It really does underline that for all the talk about an "IS Tradition" from both camps the reality is that there is no such thing as an IS Tradition. For sure, there is acres of print down through the decades purporting to be IS theory but when you look at the various twists and turns the British SWP have taken during the same time you'd be hard pressed to find any sort of continuity.
So the IS Tradition is neutral in a conflict between "state capitalist" North Korea and American Imperialism, then it is pro "state capitalist" North Vietnam a decade later. Then in the '80's it backs reactionary Islamic jihadists against the "state capitalist" USSR.
During the early stages of the Socialist Alliance the SWP is "uncompromising" on the issue of open borders and migrant rights, then when it is in a position to actually put such a position on a national platform in Respect it suddenly has nothing to say on the matter.
It is a "at the heart" of the LGBT struggle one minute but then such things become 'shibboleths' in other circumstances
It refers to the IRA as the "cutting edge" of the struggle against imperialism in the 70's and 80's but by the late 90's it has a position largely indistinguishable from the "Queens Own Socialist Party"
Now, I make no comment about the rights and wrongs of those positions in themselves, that's for another thread(s). My point is that there is no way these multiple contradictory positions can be reconciled under a political and theoretical 'tradition' beyond the fact that a certain brand name called, "The IS Traditon" held them at one point or the other.
It reminds you on a much less grander scale of Lord Palmerston's comments that Britain has no permanent allies only permanent interests. The "IS Tradition" has no permanent ideas or practice only permanent interests, which is to be as visible as possible and recruit.
Groucho Marx probably sums it up better: "Those are my principles and if you don't like them.., well, I have others!"
