Here's something I've posted a couple of times in the past but is relevant to this conversation:
When I first started here, and for a long time after, I used to go fly a buff out and take (or at least try to take) the hangers out at a field that was at one end of a "good fight". It wasn't to piss anyone off. I thought I was doing the right thing. If the fight was stalled between two bases and through bombing the enemy base our country could move forward then I had, in my mind, positively influenced the direction of the fight.
Even now it's sometimes hard to distinguish between a furball and a stalemate when flying over at altitude.
For the most part, I doubt most bomber pilots are trying to piss you off (although some may be), rather I think they consider themselves contributing to the cause.
Even if the base is taken the furball will redevelop in another location.
