Victor Davis Hanson uses his latest National Review Online column to document the negative impact of recent changes in language used to describe key aspects of American public policy.

First were the necessary changes in language. In the Obama age, as in Orwell’s 1984, the natural meanings of words had to change. See the third book of Thucydides’ history for the details.

Running up serial trillion-dollar deficits was not profligacy, but rather making “investments” for “the children.” Irresponsible borrowing became “stimulus.” Indeed, “trillion” — not a frequently used part of most people’s vocabulary before 2009 — suddenly replaced “billion” as a familiar fiscal numerical adjective. A takeover of health care that would spike premiums and ration services, devices, and procedures was aptly named the “The Patient Protection and Affordable Care Act.”

“Assault weapons” superseded “semi-automatic rifles,” even as “semi-automatic” and “automatic” were no longer distinct adjectives. The obvious purpose of rapid-fire weapons was to kill innocent children, not to protect your household from intruders, to shoot fast-moving game, or to practice a sport at a shooting range, much less to remind the government, in Second Amendment fashion, that the populace was autonomous and vigilant.

“Illegal alien” disappeared in favor of the inexact “undocumented immigrant” or “undocumented worker,” even though most illegal aliens never had proper documents of any sort, and sizable minorities of them were not working. The key was to convince the American public that millions of people had inadvertently wandered over the poorly demarcated border, all in search of work. They sort of lost track of both their bearings and their legal documents in the process. “Comprehensive immigration reform” superseded “amnesty,” as if the new proposed reforms focused mostly on hordes of brilliant Ph.D.s from the Czech Republic, queuing up to acquire legal authorization to work in Silicon Valley — rather than some 11 million or so Latin Americans who entered the country unlawfully, mostly without capital, English, or a high-school diploma.
