I anticipated Russia's invasion since day 1. However, we got some productive cooperation in place for 7 years now, so I thought Christos wouldn't be willing to shoot himself in the foot for the sake of involving himself into yet another (undeclared) war just after his own political establishment almost rebelled against him after a similar enterprise less than a year ago. He's had two Tsars assassinated in less than 5 years, so his act of war is almost suicidal for the stability of his regime.You couldn't have been surprised. As soon as the uk declared war on you I figure it was a matter of when not if Christos declared war on you. I'm not sure you can handle fighting two superpowers at once but then again Christos has worries in China so your situation isn't completely hopeless
As for us, we've been prepared for that and many other scenarios. It's not gonna be an easy war, but I'm not concerned at all regarding its result. Finally, my state will be able to do what I've designed it for: kill armed humans.
