In an ideal world, they would see the error of their ways, give up their jobs entirely, and stop supporting the military industrial murdering machine that makes this planet so insufferable for so many human beings.

In an ideal world none of society's resurces would be wasted on war machines anyway. The question is how do we go from here to there? I firmly believe that we cannot afford to simply dismiss workers in these industries. Rather we should be standing shoulder to shoulder with them in this campaign and simultaneously discussing Imperialism. One of the best examples of how this can pay off is from the 1970s. The Lucas plan was an alternative plan to turn production from miltary production to more useful things. See:

Unite against the bosses, discuss fraternally together.

I'm broadly in agreement with Nick. We have to avoid being to dogmatic in our approach. Making links with workers who are standing up for themselves and taking strike action is really important. If they're getting politicised around issues very close to home, it's not such a great leap for them to be politicised around broader issues.

If someone wants to organise an anti arms trade picket of Marshalls, that'd be great...but that doesn't mean we shouldn't support a trade union strike and picket on issues of workers rights.
