Put bluntly - no, fuck you!
You cannot blame the worker for the shit that their boss does. For most of these guys, they simply have found the nearest secure job and taken it. They are not responsible for any wrongdoing. In an anarchist society, the revolution would presumably require weapons. Who will make them? Presumably workers in weapons facories - will they still be scum then?. Like all of us (that actually work) they are forced to sell their labour to provide for themselves and their families. To blame them for what their boss does is actually classist, and the exact drivel that makes me (as an anarchist) fucking embarrased of swathes of the movement. I would be proud to stand with these guys in defence of what few rights we have won in the workplace.
The nature of employment in a capitalist society is inherentluy unethical and hierachical, so to blame this lot for what their boss does is to say that the concept of working at all is unethical, wheras in fact, it is the system that we work under that makes work bad, not the act of work itself.
To bring your argument to its (il)logocal conclusion, lets congratulate Thatcher for shutting the mines, as those bastard miners caused climate change. Also, good on the BA bosses who layed off all those Gate Gourmet workers - their production of airline food made air travel more comfortable, helping more people to fly, hence contributing to climate change.

The corect anarchist response to this situation is to recognise that these guys do work in a particularly unpleasant industry, but that any move towards workers empowerment is a good thing. If they had the choice, would these workers supply oppressive regimes with weapons etc? No of course not, but their boss would, and it is that oppressive relationship between boss and employer that needs to be challenged, no matter what industry it occurs in.
