Last Fall I gave a talk at the Heritage Foundation on the Fiftieth Anniversary of the Hungarian Revolution and it is now published. They have put it out under a "First Principles Series" and some of the other essays might interest you. My piece, alas, is a variation on a theme with which you are all too familiar. Sorry.
And yet, perhaps I shouldn’t be so surprised that the simple (although, I hope not simple-minded) themes of citizenship and assimilation of immigrants continues to press, Note this Washington Post article in which the deep question is posed: Should the U.S. Government encourage assimilation? The question is not, of course, whether the Feds should spend money on programs that encourages or teaches immigrants to become Americans. That is missing the point. Please note that in the WaPo article almost all the immigrants quoted make perfect sense (e.g.: Americans "want all the people -- black, yellow, green, Chinese," Zemikel (from Eretria) said. "In other countries, they don’t want them, like, equal.").
