Just wondering. On immortal it seems very hard to launch any kind of invasion force to the other side of the map when you got your own borders to worry about. That's excatly what happened, and when I realised that Washington is becoming a powerhouse, it was pretty much too late. My last effort was to attack him with all I got (cossacks and artillery). Only problem was that he had rocket artillery, around 25 B17 bombers which annihilated my attack force in 4 turns after first bomb dropped. I didn't have even tech to get some AA guns in the army to mix it up but waiting for them would've been too late (well it was too late already) since he would've just teched up for even better military tech. Any ideas on how to prevent certain AIs from becoming an ultimate powerhouse and being out of reach in the later game (can't out science them, destroy them or anything else)? Here's a little pic of how the world map looked when I went to war against them, met a couple dozen B17s, and lost my offensive army. Spoiler : You might go "omg you don't have oil yet" but I specifically went for dynamite, railroad, plastics approach.
