It's not practical in every case to go after a smacktalker on the other side of the cluster. People talk shit to I-RED all the time, and while we are fully capable of taking on almost any other roleplaying group toe-to-toe, we're not going to deploy to Great Wildlands because you happen to live there and run your mouth all the time. Even more likely we'll ignore you, but in the off chance you actually put some effort into your aggressive roleplaying and look like you might be fun to mess with, we'll hire mercs.
I-RED almost never wardecs others directly, and when we do, it's only because John genuinely thinks the other party can provide fun for the whole alliance.
But since people have some questions, I'll answer why we didn't wardec PYRE: We didn't need to.
Back when we lived in Syndicate we were much larger and more "dug in", while PYRE was a much smaller and more agile target and not really something worth declaring war on. I don't mean that insultingly, of course. Just that, we had already set Pyre red (we are NRDS in lowsec), and Pyre had set us neutral (Pyre was NBSI). If we were going to encounter each other, the stage was already set for a fight. We didn't
need to drop ISK on a wardec on top of that. It would be a burden on us to go find and fight Pyre on their own turf, so we never bothered to.
On the roleplaying side, we weren't interested in setting ourselves up for even more smacktalk by attacking a seemingly prominent member of the Caldari Militia directly with a very public and very grandiose wardec, which goes back to John's preference of hiring mercs. We told Pyre if they came upon us, we'd shoot them, and that was all we needed to do.
I-RED has never really been one for playing with wardecs much. We're often the subject of them, so it's not as if we don't like them - it's just not our style to declare war most of the time.
