Against the abrupt dissolution of the military-political bloc for far-fetched reasons.
You didn't recognize the state (if it weren't for the votes of Kittypink and Greatwater, Rex Ventorum wouldn't have the right to be in the Security Council, not even because he's pursuing a "bad policy," but simply because this state is being refused recognition at the political level), but you managed to start issuing some kind of ultimatum. As for "which of the two Ventorums is legitimate," the answer is simple: the one who holds power; moreover, as was written, the current consul of the FRRV hasn't gone anywhere, and therefore the secretary of security didn't actually have the authority to represent this country.
I don't think these are far-fetched reasons, and for the current leadership of the country, it's outright treason. The military-political bloc may not imply absolute agreement among members on every issue, but putting obstacles in the way of an ally is a different matter.
Actually, I'm saying this not to somehow change the relations between countries in the game (it's quite possible that such tension will positively affect activity and interest), but to point out that at the level of relations and at the level of political ethics, my country's decision was absolutely justified.
