No, I am demonstrating that even if we for some reason talk about states as if they are people, your description is not true. I may react to a friend being rude by thinking less of him. I may not. I decide how I respond, not him.
And your demonstration is completely useless with regard to countries. Especially since there is one relation score for both countries. A case when offended country would choose to keep liking the offender is not even worth serious discussion.
So now we have the very thing you once said was absurd: a country increasing relations with another country through a unilateral action even though said other country potentially does not want it.
In the OP I clearly presented example of unilateral action by a country that leads to relations increase. So yep I guess I conceded to...err... my original post? Whatever makes you feel better dude
No, actions I presented simply CANNOT be carried out against countrys will. You seriously try to argue that it might be against countries consent to lower tariffs, or renounce territorial claims on its lands? There is nothing to consent here, to begin with, its just elimination of a problem in bilateral relations. If this makes it easier for you to swallow, on example of territorial claims: it is unilateral increase through elimination of malus in relations. Dude I get it, you seem to be really obsessed with idea of me conceding to something you said, but you have to make a claim that actually makes sense.
To reiterate, I argue that it is absurd to be able to increase relations (very significantly) with whoever you want by unilateral action, and with no preconditions, and without this countries consent. What makes way more sense is the system I presented in OP - various relevant diplomatic actions, each having material consequences closely related to other mechanics. Some of them can be unilateral, some of them require consent. It is simply better idea (as shown by relatively high reaction score of my OP), and you failed to present any serious arguments to refute it.
To finish this lenghty exchange: In fact it is you who seems rather lost in this discussion - you took numerous, unrelated attempts to undermine my idea, like claiming point 2 of OP is no different from existing mechanics, other irrelevant and quite funny claims I don't even have energy to quote. You keep fixating on the issues of this unilateral relations increase, which is insignificant in relation to the topic. I suggest you divert your attention to something else, because as of now, you really didnt contribute much to the matter, apart from obsessive repetition of same arguments for last 3 pages
