The state is not the nation, so no? We became a Nation-State immediately after the Civil War however. The United States are Vs. The United States is. The industrial class imported Southern and Eastern European Catholics which transformed a solidly Euro-Protestant Nation-State into a bi-national state which happened to have Jews living in it. The threat of large non Euro immigration caused the Euro-Catholics and Euro-Protests to unite in creating a system of immigration quotas.
By and by Jewish money purchased prestige, enough to ally with the liberal WASPs against the Catholics and conservative Protestants and eventually re-open the borders to non-Euro immigration, among other things.
The US is now a prison of Nations, a multinational Empire that doesn't even benefit from a unified religious identity. And Euros of all faiths are being replaced in the land they built.
