Yeah, I agree...
PowerPlay turned the political landscape literally on a dime, with nothing happening to even remotely warranting it. And supposedly with Federal and Empire central governments not caring one bit (just think of all the economical, military and political turmoil that would cause).
And from my understanding, Powers officially sanctioning and rewarding unanimous killing of other Power's Ships within their territorial space is a clear and open act of war.
Apart from 100%-contradicting i.e. broad Alliance Policies (which until days ago shared friendly or at least neutral relations with Independents, Empire and Federation), all Powers are actually behaving like Terrorist warmongers doing that.
Just add it onto the existing pile of "doesn't make any sense" and move on....
