Donald Trump’s immigration paper asserts, as “core principles,” that “there must be a wall across the southern border” because “a nation without borders is not a nation.” And it argues that “any immigration plan must improve jobs, wages, and security for all Americans,” because “a nation that does not serve its own citizens is not a nation.” Many have observed that America has never had a wall across its southern border, and that no immigration plan has ever improved wages and security for all Americans. By Trump’s logic, America has never been a nation.

One wonders what he calls the country that allowed his ancestors to immigrate here.

He is of German stock on his father’s side.

Prior to his grandfather’s arrival, plenty of immigration restrictionists believed, not without reason, that German immigration had irrevocably changed their communities.

As one example, consider what took place in Cincinnati, Ohio.

“In the 1840s and 1850s, Cincinnati society became increasingly unstable as German and Irish immigrants poured in,” The Cincinnati Inquirer reported in a historical retrospective. When an Italian emissary of the Pope visited in 1853, “German Catholics took to the streets armed with guns, pistols, clubs, canes and sling shots trying to run Cardinal Bedini out of town. The Germans, many of whom fled to the U.S. after the failed European revolutions of 1848, saw the priest as a symbol of repression.”
