The well-stuffed slave masters currently gorging themselves in Cuba's halls of power need to be held accountable.

Starting as a few bands of hunter-gatherers, humanity expanded the food resources afforded by the land a thousandfold through the development of agriculture.

If we are to assess the rationality of government expenditures to protect the lives of Americans through massive domestic surveillance, we need to compare this program to others aimed at saving American lives.

Europe certainly needs a genuine conservative movement to combat the creeping bureaucratic collectivism that is stifling the human potential of the Continent.

As a result of the carbon-dioxide enrichment of the Earth's atmosphere, plants are now growing faster. Furthermore, global warming lengthens the growing season and increases net rainfall.

The United States has the largest and best navy in the world.

The Earth is not endangered by humanity. But humanity is being seriously threatened by those who follow the guides of the WWF.

In the courtroom of science, if you have the facts on your side, you don't need a gun - and juries would be well advised to distrust the case of those parties who choose to use weapons to silence adversarial witnesses.

In the wake of the disaster caused by Tropical Storm Sandy, various allies of the Obama campaign have rushed to claim that the event was caused by anthropogenic global warming, thereby justifying the president's program of crushing the economy with regressive carbon taxes, a supposedly necessary measure to prevent future bad weather.

The goods of the world market are available for Cuba to purchase, but all the foreign exchange is monopolized by the regime, which uses it for its own power and pleasure.

The federal government was created to defend the United States, not to wage war upon it.

Traditional Marxism attempted to argue against free enterprise by saying that capitalism causes poverty and that, therefore, socialism is necessary. That didn't work, because it was false.

Instead of forcing everyone to buy health insurance, Congress should pass a law protecting the uninsured from being charged more than the insurance companies are for a given service.

The danger facing us comes not from lack of resources, but from people who insist that we have run out of resources. If you embrace their idea of a world where there is only so much to go around, then you are endorsing a program of genocide and a war of all against all.

In their efforts to discredit human freedom, the Putinites denounce the sins that may occur under the reign of liberty with the same ardor, the same sincerity, and the same purpose that animated their Soviet forebears.

What Russia really needs is not gay rights but human rights, and the rule of law.

The more that energy costs, the less economic activity there can be.

Putin is sometimes described as a revanchist, seeking to recreate the Soviet Union. That is a useful shorthand, but it is not really accurate.

The Soviet Union used the exploitation of workers under capitalism as an agitational issue to subvert Western democracies even as it practiced slave labor at home.

Western environmentalists might value their independence, but their organizations are largely donor driven, and if he wanted to, Putin could have a lot to donate.

The 20th century saw three great-power confrontations. Two of them turned into total war. We lucked out on the third. Do we really want to roll those dice again?

I grew up in the 1960s and wanted to become part of the great space exploration effort, but when I graduated from college in 1974, the Apollo program was over, and the country had moved into this pessimistic mode. We had entered the 'age of limits.'

When the government mandates that everyone must buy a product, its sellers can, and will, increase its price, potentially without limit.

The bedrock foundation of any rational immigration policy should be to benefit America rather than benefiting potential or existing immigrants, or any other specific group, whether favorable or antagonistic to them.

The revelation that the National Security Agency has been secretly amassing data on countless law-abiding American citizens has aroused great concern about the potential threat such an effort poses to liberty.

Government attempts to ban fracking should be aborted. The government should lift the burdensome regulations that have made the construction of nuclear power plants excessively expensive, thereby freeing up even more natural gas for direct use or for methanol manufacture.

The policy of the Obama administration is to employ regulatory strangulation to drive up the price of energy. This must be exposed and opposed for what it is: a policy of forced economic contraction.

It should be noted that the EPA's banning of methanol is categorically absurd from the point of view of environmental protection.

The EPA could act to open the transportation-fuel market to vigorous competition from natural gas as well as coal, biomass, and trash, by legalizing methanol. This would force oil prices down, expand the economy, and create millions of jobs.

We need to drastically reduce the importance of the petroleum game itself by enacting flex-fuel-vehicle legislation that will open the transportation market to fuels derived from non-petroleum sources.

No one can prevent hurricanes, but prosperous communities are much better able to withstand them than poor ones.

Can we achieve 140 mpg fuel economy? You bet. Just get the bureaucrats out of the way, and Yankee ingenuity will do the rest.

The United States should give former NSA contractor Edward Snowden immunity from prosecution in exchange for congressional testimony.

Through our CO2 emissions, we are making the earth a more fertile world.

The EPA must be forbidden to seize or destroy the property of any person until and unless such person has been found guilty of a crime in a court of law.

The problem with Russia is not corruption per se, or even Putin per se. Russian government is not corrupt because Vladimir Putin has absolute power. Russian government has been corrupt and will always be as long as anyone has absolute power.

People make their own fates, and if enough of us make our fate to be space explorers, perhaps we can actually get some space exploration done.

The U.S. trade embargo on Cuba is almost completely ineffective, as many other countries, including the European Union, do not honor it.

The Yanukovych regime is a mafia, which regularly threatens, imprisons, murders, or disappears political opponents as well as those whose possessions it covets.

As I explain at some length in my book 'Energy Victory,' during World War II, the American strength in oil production was a decisive advantage for the Allies. Airplanes, ships, and tanks all ran on oil, and we controlled the supply.

Nothing could do more to help the world's poor than to make fossil fuels cheap and plentiful.

Every dollar added to the price of oil weakens America and strengthens her enemies.

In addition to virtually banning methanol outright, the EPA has created regulations to prevent cars from being modified by small businesses to optimize their performance, including through the use of methanol.

Some conservatives say that whether it's popular or unpopular, imposing strict limits on immigration is the right thing to do, and it must be defended.

The problem is that the automobile companies are not independent entities capable of pursuing their own interests. Rather, they are owned and controlled by organizations that are much more heavily invested in oil.

Putin and many of his gang may have once been Communists, but they are not that today. Rather, they have embraced a new totalitarian political ideology known as 'Eurasianism.'

Putin himself made his original fortune in the early 1990s, when he stole the funds that had been entrusted to him to buy food in Europe to relieve the starvation in Leningrad that occurred during the economic collapse following the fall of the Soviet Union.

The issue comes down to this: The NSA metadata-collection program costs lots of money, and had funds not been expended on it, they could have been used to support other programs that might have been far more effective in saving American lives.

If the auto companies were free agents, they would act to break the fuel monopoly that is so damaging to their own interests and those of their customers. But they are not, and so they won't.
