Ben Franklin and Lafayette would like to argue about French relevance to the US outside of as an adversary.This is one of those times where you kinda have the right idea, but also, no, the US is almost purely Anglo in origin. Also, it wasn't Spanish and Portuguese, but Dutch and German that were the other major European influences on early America. We eventually took over a bunch of former Spanish Empire territory, but by that point much of the American culture and history was set and it was well after the US Revolution. And we purchased Alaska from the Russian Empire, but the Portuguese didn't ever hold any north American territory, it was outside their remit from the Pope.
Spain, as far as the US is concerned, only matters in that they triggered the Columbian Exchange. All the early US colonies were settled by English, Scottish, and Irish immigrants from those islands, as well as some German colonists in Pennsylvania. The Dutch influence was very light overall, as while they settled New Netherlands, that colony was taken from them by the English becoming New York... and then run for many years that way, quite divorced from Dutch influence. France didn't really get involved save as an adversary, oh, and their trade with the natives triggering the Beaver War around the Great Lakes which caused a massive migration south by the losers who displaced other tribes thus triggering a fuckton of Indian Wars in the 17th century that both did and did not involve the British colonies.
But the US legal and cultural institutions from Colonial times are very purely British. We have Sheriffs and Counties for goodness sake as our most local political organizations for most States.
As would most of the west side of the Mississippi.
