<i>America is already pretty anti-immigration</i><p>It has failed miserably, then. Of course, there were land law and exclusion acts enacted as legislation throughout history. Nonetheless, the USA&#x27;s arrangement of basing citizenship on the principle of <i>jus soli</i> as opposed to <i>jus sanguinis</i> means its identity is a national&#x2F;soil-based one and not an ethnic bloodline division, making it nominally inclusive. Hard nativism is a rather rare sentiment these days, too.
