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.

A country that cannot count its own illegal aliens - estimates range from 8-12 million - with a porous 2,000 mile border is not secure despite twelve carrier battle groups. We must accept that it is a cornerstone of Mexican foreign policy to export illegally each year a million of its own to the United States to avoid needed reform at home and to influence American domestic policy.

Donald Trump, he didn't dismantle Eastern European missile defense. He didn't go to Geneva and press a plastic red button. He didn't make fun of Romney for saying Russia was an existential enemy. He didn't have a hot mic exchange with a Russian President saying that he would be more flexible with the Russians after the elections.

[People] are alike in a sense that the Bernie Sanders anger at Hillary Clinton was that she was a so-called progressive and yet had managed to make $125 million.

Offering 'comprehensive' reform usually means years of arguing and horse-trading among pressure groups to get anything done. By the time all the special interests are appeased or bought off, the resulting elephantine legislation typically looks nothing like what was intended. In short, big-government medicine usually doesn't work on big-government sickness. If President Obama wants 'comprehensive' change, it would be better simply not to spend any more money we don't have.

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.

Gas prices in many parts of the country are nearing $4 a gallon; it could get even worse as unrest spreads throughout the oil-exporting Middle East. Yet the Obama administration once again seems to see no crisis. It has curtailed new leases for offshore oil exploration for seven years and exempted thousands of acres in the West from new drilling. It will not reconsider opening up small areas of Alaska with known large oil reserves.
