Actaea

Well, it's worth a try.

Even though I have a monarchy, and political freedoms took a bit of a hit yesterday, yesterday it was written like this:

The compassionate population of 23 million The Great Waterians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

Therefore, I don't see anything wrong with inviting my socialist comrades to negotiations.
I invite The Armed Republic of Sciencecracy and The Colony of Aghar to visit my hospitable country with its stunning nature. I just happen to have a country residence for important negotiations with an appropriate level of security. There will be an opportunity to discuss the details of an alliance agreement (military alliances can be different), and if desired, to sign it. I also invite the Minister of Education of Sciencecracy (or whatever you call him) to come. I have some thoughts about another document.

In general, I have sent the official invitation, and whether or not to come is up to you.
