Some history can be ignored. The Roman Empire isn't coming back.

But Greater Persia has just as much history trying to take over Turkmenistan as the Russians. Throwing in the UK might be a bit much though, their style emphasized puppets instead of directly taking that land.
Uniting Scandinavia seems dubious, but if Sweden has that ambition there's no reason for Finland not to have it.
The Ukraine is in a very strong starting position, but lacks any outside cores at all.
Germany lacks cores in the Habsburg lands and even on Memel. There's very little incentive to expand South, compared to taking those French, Dutch, and Swedish lands.
The war between Germany and France started I think from the second option, uniting the volk. France simply brought too much to the table for Germany, but Germany was able to toe the line indefinitely.
The Mexican civil war happened well, but the US landscape was an absolute mess in the end, a real hodgepodge. Some event after the war should set up sane boundaries. Instead of a big anti-British alliance, the Scots simply marched down and took over.

The US was easily able to then take New England, and Angola gobbled up the UK's African colonies. It was bizarre.
I had a much easier time with one dimensional Angola (I was Ottomans) because of their complete lack of a navy. Their land units were tough but it was simple to take their wealthy coastal provinces with my destroyer fleet.
