Tbh, I kind of feel like there's not much visible anarchist presence on a lot of demos nowadays.
Well, on an immediate sense, Palestinians in the Gaza Strip who want to see a ceasefire (or a proper ceasefire that doesn't involve the cops firing tear gas at a mosque hours after the ceasefire's announced) and Israelis who want to see a ceasefire have a pretty obvious immediate common interest there. Beyond that... idk, groups like
Standing Together or
Koah LaOvdim would be able to answer that better than I can. I think a lot depends on the fortunes of the class struggle, like it's easy to assume a shared interest between Israeli workers and their ruling class but we shouldn't forget that the wave of uprisings around the Middle East in 2011 included
a series of mass protests in Israel around housing that acted pretty explicitly as a class movement, making demands on/opposed to the Israeli state.
Obviously, there's never any
guarantee that these kinds of interests will triumph over nationalism, just like there's never any guarantee that the British working class will ever stop voting the tories back in. But I don't think the population of any other country anywhere in the world is doomed to
always choose nationalism, and I don't see why those living in Nablus or Tel Aviv have to be the exception to that.
