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

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.

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

The key issue is not who is in charge but what. Russia's problem is constitutional. There is no division of powers. The judges, the police, and the legislature all work for the same people, and there is essentially no trial by jury. As a result, anyone can be arrested and accused of anything, and conviction is almost guaranteed.

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

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 use of hunger as a weapon of political control is a crime against humanity.

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

Without Ukraine, Dugin's fascist Eurasian Union project is impossible, and sooner or later, Russia itself will have to join the West and become free, leaving only a few despised and doomed islands of tyranny around the globe.

The Putin regime's income comes from oil and gas exports. If we could crash the price of these commodities, we could bankrupt the regime.

The federal government should end its policies of economic warfare against the United States and allow our nation to develop all its energy resources to the fullest, both for domestic use and for export.

The blockade against American natural-gas exports needs to be lifted, and the war on coal needs to be ended, so that, instead of being wasted to replace perfectly good coal-generated electricity, our natural-gas exports can be expanded even further.

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.

Our European allies need to be able to buy our fuel, or they will fall to enemy domination.

Like the producers of crops, airplanes, and books, producers of natural gas provide goods to meet the size of their available market. The larger the market, the more they can produce, and the more revenue they can obtain to cover their fixed costs and invest in future development.

Science is not a collection of facts; it is a process of discovery.

Before agriculture was invented, land was not a resource. Before oil drilling and nuclear fission were invented, petroleum and uranium were not resources.

The space program needs a goal, and the goal should be humans to Mars.

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.

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

Mars is key to humanity's future in space. It is the closest planet that has all the resources needed to support life and technological civilization. Its complexity uniquely demands the skills of human explorers, who will pave the way for human settlers.

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.'

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

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.

By enriching the carbon-dioxide content of the atmosphere from its impoverished pre-industrial levels, human beings have increased the productivity of the entire biosphere - so much so that roughly one out of every seven living things on the planet owes its existence to the marvelous improvement in nature that humans have effected.

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.

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.

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.

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.

Would offering the Mars Prize damage NASA? I don't think so.

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

Putting aside for the moment the question of whether human industrial CO2 emissions are having an effect on climate, it is quite clear that they are raising atmospheric CO2 levels. As a result, they are having a strong and markedly positive effect on plant growth worldwide. There is no doubt about this.

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.

Prosperous communities are much better able to survive hurricanes or other natural disasters because they have greater resources, both public and private, to fall back upon.

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.

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.

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

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.

There is nothing 'conservative' at all about Putin's cause. What he is offering is a synthetic ideology called Eurasianism, composed for him by Dugin, as a means of uniting all the anti-Western movements of the world under Kremlin control.

Federal lawmakers need to change the rules so that vehicles converted to use new fuels can be put on the road; the only restriction should be that they pass the same standard state tests that all other cars do.

I don't think we should have to do a Mars mission on the basis of hysteria. I think we should do a Mars mission on the basis of a deliberate judgment that what we want to do is open up a new planet for humanity... that we are continuing to be a nation of pioneers.

Nothing could be more regressive than carbon taxes.

In the 1940s, the petroleum business was an American game, and it was enormously to our advantage that the world ran on oil.

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?

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

You can't 'control' a Mars mission from Earth. The Mars mission is going to have to be controlled by the people on Mars... There is just too much involved that is out of sight of Earth.

The largest automobile company in the world is Volkswagen. Who owns it? The answer is the government of Qatar.

I run a small company with 18 employees on its payroll.

Ireland never lacked the capacity to feed its people. During the entire 'great famine,' the island continued to produce massive amounts of beef and grain. The Irish just couldn't afford to buy any of it due to the enforcement of rack-renting, high taxation, and suppression of manufactures.

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