Marked points are either to be left or to be removed in the future.
As for Liberty, situation is just temporal there. As I said, embargo is just for a period of time. However, we in fact cannot fly though Liberty to Bretonia because of using Rheinland stuff (until KTA gets reply from Liberty's head). So, we can say that KTA is as unwanted in Liberty as Junkers are unwanted in Kusari.
Oh and most of routes we are making now are filght through... Rheinland. Yeah, I couldn't believe myself that getting to Bretonia would be as fast (is not faster) as going through Liberty. But for now, we rather enforce Rheinland-Kusari trade with no trade within Liberty Space. Getting Tea from Cortez is pain, however.
As for T&T, officially we are not in Liberty space... this wouldn't stop us from visiting Tinkers Haven from Galileo/Hudson side.
Privateers were supposed to be volountaury so-called "defenders" of KTA against rather unfriendly Liberty, but I think I will have this idea scrapped.
