I mean, will there be an option to "contain" it somehow as other countries in a realistic manner? In the original Victoria, it had cores all over most of it's present territory from the begining, when in reality the USA wasn't planning to expand exactly how it did.
For example, if Mexico keeps Texas, there should be no Mexican-American War (and the USA AI should not be a warmongering bastard against Mexico in such case). The cores of the USA at the beginning should be only the territory they controlled in 1836, and then only if and when Texas succeeds in it's independence and joins the USA, it would receive Mexico's northern territories as cores. Similarly, Mexico should have those territories as cores at the beginning, losing them only if Texas manages to secede.
Also,in the ACW, if the Confederacy manages to survive the war, then there is no reason for the Union to keep going at war with it constantly every five years, when in such a scenario the CSA would be recognized as an independent state by the Great Powers. If the CSA survives, USA should lose all cores on it.
