Wouldn't that make those folks harangue him even harder for successfully convincing some to join the 'dark side' or something?

Though that would be assuming these folks have consistent goals regardless of temporary advantages.

Maybe some are so wishy washy that they would degenerate weapons manufacturers one day and praise them the next if it's for a cause they perceive to be beneficial. (And then switch back to degenerating asap)

I wouldn't be able to bring myself to respect such craven losers. If enduring that is what it takes to succeed in the defense sector or the peace movement then kudos to anyone who tries in either.
