Rolf Ekeus, his appearance can deceive. He looks somewhere between an international diplomat and a mad professor. He's got that sort of shock of white hair and a slightly absent-minded way of speaking. But he's extremely sharp and very serious about power relationships.

Iraq has, in effect, one export of any consequence. That's oil.

Scott Ritter is a very well-known archetype of a certain U.S. military officer. Very hard talking, very ambitious, zealous, and completely consumed with carrying out his mission. He's a guy who, throughout his career, I would say, did not break rules, but he worked around road blocks.

In effect, you cannot stop Iraq from growing nasty bugs in the basement. You can stop them from putting operational warheads on working missiles and launching them at their neighbors.

The National Security Agency has broken privacy rules or overstepped its legal authority thousands of times each year since Congress granted the agency broad new powers in 2008, according to an internal audit and other top-secret documents.

Privacy and encryption work, but it's too easy to make a mistake that exposes you.

NSA surveillance is a complex subject - legally, technically and operationally.

The NSA is forbidden to 'target' American citizens, green-card holders or companies for surveillance without an individual warrant from a judge.

U.S. intelligence services routinely use collection methods against foreigners that foreseeably - with certainty - ingest high volumes of U.S. communications as well.

Some misunderstandings are hard to cure.

As militias go, the Ohio Defense Force is on the moderate side.

Scores of armed antigovernment groups, some of them far more radical, have formed or been revived during the Obama years, according to law-enforcement agencies and outside watchdogs.

The federal government is often said in militia circles to have made wholesale seizures of power, at times by subterfuge. A leading grievance holds that the 16th Amendment, which authorizes the federal income tax, was ratified through fraud.

Obama's ascendancy unhinged the radical right, offering a unified target to competing camps of racial, nativist and religious animus.

Holding our own government to account for the use of its power is, in my view, the highest mission of a U.S. news organization.

I have no evidence of any relationship between IRS and NSA.

I'm a journalist and author. I make my living by finding things out and writing about them.

Why does it appear that interested readers so often attribute flaws to 'the press' rather than taking particular issue with particular reports?

In general, states do not count on pledges of 'no more war' from their neighbors. Israel's army never counted on it from Egypt, for example.

Palestinians have had to live for a long time with the fact that Israelis had power over them in their everyday lives.

All Americans are dependent for their energy on the Arabian peninsula.

Doctrines don't govern policy. They provide a conceptual framework by which policymakers approach their decisions. But there is no such thing as a doctrine that controls policy in every way.

Clinton saw himself much more as the steward of alliances and of consensus that moved in the right direction. He didn't see himself as someone who could change the overall thrust, I think, of global policy.

I doubt there's any government in the world that guides itself primarily by strategy or conceptual documents or worldview. Anybody who has the reins of power has to look at practical limitations and tradeoffs - the fact that you can focus at most on one or two things at a time, that resources are limited.

Snowden has yet to tell me anything that was a fact that I have been able to rebut or that anybody in the U.S. government I have talked to has been able to rebut.

Daniel Ellsberg showed tremendous courage back in the '70s.

Snowden has been very sparing about discussing his early life or his personal life.

The surveillance of ordinary people is far greater than I would have imagined and far greater than the American public has been able to debate.

Cheney was among the best secretaries of defence the country has ever had. He was a very effective White House chief of staff. He did not make many enemies, and he had the ability to persuade people with that soft tone and very reasonable style of his. He's always been exceptionally good as the right-hand man.

I don't think Cheney started off in 2000 with a burning desire to become vice-president. I think the prospect gradually became more appealing, and he goosed the process.

The funny thing is that Dick Cheney has done more than anybody in the White House for quite a long time to throw up roadblocks against future historians.

No one ought to be under any illusion that Cheney privately thinks himself a failure.

Ecuador has never stated flatly that it would give asylum to Edward Snowden.

There's a long history of private-company cooperation with the NSA that dates back to at least the 1970s.

The first reports of AIDS closely followed the inauguration of President Ronald Reagan, whose 'family values' agenda and alliance with Christian conservatives associated AIDS with deviance and sin.

Early in 1986, the World Health Organization in Geneva still regarded AIDS as an ailment of the promiscuous few.

Throughout the early and mid-1990s, the Clinton administration debated the merits of paying for AIDS testing and counseling of vulnerable populations overseas.

In the wealthy industrialized nations, effective drug therapies against AIDS became available - AZT as early as 1987, then combinations of antiretroviral agents in 1996. The new drugs offered hope that fatal complications might be staved off and AIDS rendered a chronic condition.

The first and pivotal negotiations over global access to AIDS drugs began in Geneva in 1991. They lasted two years, but confidential minutes suggest they were doomed the first day.

Drug manufacturers could afford to sell AIDS drugs in Africa at virtually any discount. The companies said they did not do so because Africa lacked the requisite infrastructure.

In Africa through the 1990s, with notable exceptions in Senegal and Uganda, nearly all the ruling powers denied they had a problem with AIDS.

In 1995, Glaxo bought Burroughs Wellcome and became the presumptive leader in AIDS therapy.

For a decade, makers of AIDS medicines had rejected the idea of lowering prices in poor countries for fear of eroding profits in rich ones. The position required a balancing act, because the companies had to deflect attacks on the global reach of their patents, which granted exclusive marketing rights for antiretroviral drugs.

The modern era of continuity planning began under President Ronald Reagan.

Of all Iraq's rocket scientists, none drew warier scrutiny abroad than Modher Sadeq-Saba Tamimi.

The defection of Hussein Kamel was a turning point in the U.N.-imposed disarmament of Iraq in the 1990s.

If Iraq had succeeded in spray-drying anthrax spores to extend their life and lethality, that would have been among the most important secrets of its wide-ranging weapons program.

In late 2003, the Bush administration reversed a long-standing policy requiring agents to destroy their files on innocent American citizens, companies and residents when investigations closed.

A national security letter cannot be used to authorize eavesdropping or to read the contents of e-mail. But it does permit investigators to trace revealing paths through the private affairs of a modern digital citizen.

On average, since 9/11, the FBI reckons that just over 100,000 terrorism leads each year have come over the transom. Analysts and agents designate them as immediate, priority or routine, but the bureau says every one is covered.
