inrp, you can assume you have carte blanche wherever you want, but as much as you may feel you have rights everywhere, you don't have rights in the areas that CR feels as being under their interest. In this particular case, we have asked you not be a nuisance, and you are - we were nice about it the first time, and the second time we told you to get out or we'd shoot you - the third time was when Concordia logged to basically say "three strikes, your out" - As for declaring war, thats not the intention - its more of a "hey reinhardt, one of your cruisers was being a derp, and refused to leave our space, and was attacking people when we told it to leave - it opened fire, we blew it up, sorry - but next time, keep your cruisers out of our front yard, and we wont have an issue" - if rheinland wants to declare war on us for blowing up one of its military intelligence cruisers, then its perfectly fine with us.
As for your surgical strikes threat - having something to shoot that isnt vaporware gallia, would be fine with us too.
After all, you want to get offended by my explanation as to why your now persona-non-grata in CR turf, then good for you.
