I think what a lot of European countries lack is a lot more federalism (which we need to restore more of as well).
Unity in our “democratically” organized multi-party modern states should be a unity in diversity and Liberty, where we are joined essentially in our right to Liberty, and so much so that we respect, and do not try to crush, diversity. We stay “united” because we share and respect the Liberty that belongs to each other.
Within that, pride in one’s identity drawn from a heritage is NOT, or need not be, a call for separation, and is consistent with respect for our diversity.
More federalism and less unitary states is what is needed.
