Multiculturalism is a good reminder that when standards are relative, there are no standards at all.

We're in a very Orwellian situation where when we - we've slashed defense. And we've raised taxes. And we consider $600 billion annual deficit success because it's not $1 trillion.

The problem with deterrence - apparently sometimes forgotten by our former presidents - is that it is not static, but a creature of the moment, captive to impression, and nursed on action, not talk. It must be maintained hourly and can erode or be lost with a single act of failed nerve, despite all the braggadocio of threatened measures. And, once gone, the remedies needed for its restoration are always more expensive, deadly - and controversial - than would have been its simple maintenance.

Illegal immigration is praised only by those who benefit directly from it, whether in the familial sense of inexpensive nannies, cooks, or gardeners; or in the corporate interest of cheap labor in the hospitality industries, agriculture, and construction; or in the political sense of new liberal constituents; or in the tribal sense of expanding the so-called La Raza base. But the vast majority of Americans accept that when federal law is ignored, chaos ensues.

Western societies from ancient Athens to imperial Rome to the French republic rarely collapsed because of a shortage of resources or because foreign enemies proved too numerous or formidable in arms - even when those enemies were grim Macedonians or Germans. Rather, in times of peace and prosperity there arose an unreal view of the world beyond their borders, one that was the product of insularity brought about by success, and an intellectual arrogance that for some can be the unfortunate byproduct of an enlightened society.

Did either the nonexistent or the measured response after a series of attacks on Americans the past decade - in Lebanon, Africa, Saudi Arabia, New York, and Yemen - suggest to our terrorist enemies that it was wrong and unwise to kill reasonable and affable people, or did the easy killing imply that self-absorbed and pampered Lotus-eaters would not much care who or how many were butchered as long as it was within reasonable numbers and spread out over time?

Obama's immigration legacy will be the juxtaposition of his serial insistence that he was not a king or an emperor, and could not contravene the Constitution by granting a blanket amnesty, with his efforts to do just that when it was no longer politically inexpedient. I don't think a president has ever quite so habitually warned the country of the dangers that would soon emanate from himself.
