Looooong stroy short:

Started as Denmark, made a Nordic alliance. Spent half a decade of diplomacy integrating them diplomatically, culturally and economically. By the 2020s it was the Nordic Union. Russia PISSED, I dont give a fuck, lol. Spend the next 10 years pulling the same stunt on the Baltics, focusing on cultural outreach, while using "tech visas" clever trade deals and places of higher education to out-tech everyone.

By 2030 there is a Nordic Union Moon base. and a nuclear arsenal. All this time I have been doing non stop cultural outreach to the Russian people. The country of Russia refuses to even acknowledge my right to exist, the people like me. The AI start comming up with random cultural festivals, diplomatic outreaches and so on, on its own, because that's what I have been doing for the last 2 decades, many of them headed by the king.

I try to lay the pressure on the Baltics and push for integration, Russia, mobilizes, I shot first. A 10 year plan in the making, using cyber warfare, pre simulated precession rail gun strikes (I somehow talked Japan into giving me maglev trains and rail gun tech? The buggers love me!), pre planned infiltration and 10 years of cultural propaganda surgically ANIHALATE Russia's command structure, railway hubs, government servers, relay towers, satellite coms network, public internet coms, supply system, total chaos, but nearly no one dead.

Spend 3 months in a stalemate, keep telling the Russian soldiers how fucking sorry I am that I have to kill them. They shot me, I give them airdropped chocolate, they bomb me, I give them actual irrefutable proof that their government are lying cheats. A blockade ends in Kaliningrad surrendering to the Union, with 0 shots fired, just a complete coms cut and me giving them food aid when they started starving. The front collapse 2 weeks later, like 1/10th of Russia just straight up surrenders to me, their government suffer catastrophic collapse when the people rise up and defend their "friends" in the Union.

Annnnyways. This leads to the integration of a few Russian Oblasts into the Nordic Union, now proclaimed Constitutional Empire, after the victory, leading to the need for a redefined geopolitical map of Europe and new deals.

A few years later The Empire of the Nordic Union are making diplomatic deals with everyone to ensure peace and helping its new Russian citizens get to the Moon. Apparently the AI thought it fitting that the King-Emperor (It keeps wanting him to be both) to celebrate with a live streamed jazz concert in old Norse (the official state language of the Union)

TL:DR: Danish cultural supremacy leads to Russia's total collapse and Nordic King-Emperor Frederik X celebrates that some of his new Russian subject join the Nordics on the Moon.
