shows how it is mistaken, I think. It depends on the belief that somehow military intervention could be an act on the part of the western left, that the western left could force western states to intervene even if the states did not wish to. I don't think that's the case. Western militaries do not act on behalf of the western left, so nothing they do can possibly be an act of solidarity from that left.
Now, it may be that there is nothing the western left can do in solidarity with the Libyan rebels, and in such a situation we might be glad that someone else is acting where we cannot; but this would be a humanitarian consideration, not a matter of solidarity. Or you might argue that, in this instance, whatever interests are leading the west to intervene happen to align with left-wing interests, so the intervention should be supported; but this is a kind of left realpolitik argument, again, not an argument on the basis of solidarity.
So solidarity with the Libyan revolution doesn't demand that we support western military intervention, because such intervention is not an act of solidarity from us.
> "Solidarity is an activity, not a passive condition.
This is true - but supporting western military intervention is passivity, not activity. Furthermore, I don't see how you can put forward western military intervention as active solidarity by the western left without presupposing that western militaries sometimes act, and can be made to act, in ways which are not in the interests of western powers. This seems to me to be wrong, and I think believing it or encouraging people to believe it, would be a serious mistake.
