Peace at last
Winter, 1968 A.D.: Greece sends forces down out of the mountains from Herakleia to attack Salzburg. Almost simultaneously, Firestar I is dropped on Hamburg. Half of the city's population is killed, and the Greek army is decimated. Word begins to spread quickly of the devastating Norse weapon.
The city isn't gone, but I have drastically reduced its ability to produce anything. In addition, everything for two tiles around it will be covered in fallout that prevents the building of land improvements (which were also destroyed) until Greece researches the technology to clean it up.
1969 A.D.: The Greek naval base at Chios is destroyed. Back at home, word of the bomb begins to turn popular opinion against the war--especially in Germania, as Hamburg was still home to many ethnic Germans when it was hit. The pro-peace Restoration Party gains power in the Norse parlaiment, and talks begin to bring an end to the conflict.
It's about time to call this war done. I've captured four Greek cities and destroyed four more, losing none of my own in the process. I hit a ninth hard enough to turn it from a metropolis to a backwater, and proved my point to the world that I'm just as much a military force to be reckoned with as anybody. I don't need to wipe Greece out completely to ensure that I'm the dominant superpower, and I don't plan to. They've lost more than enough to derail their progress toward victory.
1970 A.D.: A peace accord is finally reached with Greece. The DMZ between Hamburg and Tunsberg remains in effect, with the NDU-installed North Greece provisional government as its stewards. the Greek settlers at Herakleia are allowed to remain there, although travel outside and through Norse territory is heavily restricted.
Okay, Herakleia can't stay there. Almost as much for obsessive compulsive reasons as safety ones, I will not abide a little foreign dot in the middle of my empire. If I'd had more troops in the area, I would have captured it really quick before making peace, but it was going to be a pain as most of my forces were in the South and Southwest. So, at some point, I'm going to be at war with Greece again to deal with that. Hopefully briefly.
The new Norse premier gives a speech praising the overwhelming victory against what had been a dangerous and corrupt enemy, but also lamenting how far things went before peace could be made. The Norse Democratic Union is stronger than ever, now including most of what were once the sovereign nations of Austria and Germany. Greece's dominance in the West has been shattered, and the Norse people have proved that they can outfight a numerically-superior foe on every front. Her closing wish is that they can continue to be as brave and victorious in peacetime as they were in war.
