Host Scott Simon catches up on the week's sports with NPR's Tom Goldman.

In his national security speech Thursday, President Obama discussed drone warfare and the Guantanamo detention camp. But a third controversial issue went largely unmentioned: the use of interrogation methods that are tantamount to torture.

As investigators look into the Boston Marathon bombings, one crucial question is whether the suspects, brothers Tamerlan and Dzhokhar Tsarnaev, acted alone or had help. The clues might be found in the bombs used.

From what is now known, it appears the brothers assembled a whole arsenal of explosives. Watertown Police Chief Edward Deveau told CNN last weekend that the suspects had at least six bombs, including the two used in the attack and one thrown at police during a shootout.

As Venezuela's president, Hugo Chavez thought in grandiose terms, and his country's vast oil riches enabled him to act on his vision. But Chavez died before he had to deal with the flaws in his model, and some hard choices await his successor.

Key to Chavez's notion of "21st Century Socialism" was the redistribution of Venezuela's oil earnings. The country's oil reserves — estimated by the Organization of Petroleum Exporting Countries to be the largest in the world — are worth tens of billions of dollars a year in potential revenue.

You might think alarm bells would be sounding in Washington, given the warnings coming out of North Korea. But when they talk about North Korea, U.S. officials are sounding like exasperated parents responding to a child's tantrum.

At the White House on Friday, spokesman Jay Carney said the United States "would not be surprised" if North Korea actually carries out a missile test.

U.S. government pronouncements about the danger of a major cyberattack can be confusing. The director of national intelligence, James Clapper, and the head of the U.S. military's Cyber Command, Army Gen. Keith Alexander, delivered mixed messages this week while testifying on Capitol Hill.

James Clapper, the director of national intelligence, went before the Senate Intelligence Committee on Tuesday in a bit of a sour mood. He led off complaining that he had to speak publicly at all.

"An open hearing on intelligence matters," Clapper said, "is a contradiction in terms." And then, before getting to any international problems Clapper hit a domestic one: the spending cuts mandated under the sequestration package.

U.S. companies that have their networks routinely penetrated and their trade secrets stolen cannot be surprised by a new National Intelligence Estimate on the cyber-espionage threat. The classified NIE, the first-ever focusing on cybersecurity, concludes that the U.S. is the target of a major espionage campaign, with China the leading culprit.

There have been security flaws in software as long as there has been software, but they have become even more critically important in the context of cyberweapons development.

With the Pentagon now officially recognizing cyberspace as a domain of warfare, U.S. military commanders are emphasizing their readiness to defend the nation against cyberthreats from abroad. What they do not say is that they are equally prepared to launch their own cyberattacks against U.S. adversaries.

President Obama's nominee to run the CIA has his confirmation hearing Thursday afternoon. The hearing of White House counterterrorism chief John Brennan comes as lawmakers are studying a memo on drone strikes overseas. Robert Siegel talks to Tom Gjelten.

John Brennan, President Obama's choice to lead the CIA, can look forward to a grilling Thursday on Capitol Hill. As Obama's chief counterterrorism adviser, he has been associated with some controversial policies, including the use of armed drones. Brennan's nomination comes before the Senate Intelligence Committee, and members from both parties have their questions ready.

A week has passed since the terrorist attack on a natural gas facility in Algeria, but risk analysts and security experts are still undecided about the incident's likely impact in the energy world.

The price of oil, a good indicator of anxiety in the energy market, went up modestly right after the attack, but then it stabilized. No energy company has suspended operations in Algeria, nor has any company announced it will hold off on future investments in North Africa, a key source of oil and gas supplies.

With time running out on efforts to monitor Iran's nuclear program, 2013 could well be the year when the United States must decide whether to take military action to block Iran from acquiring a nuclear weapon.

President Obama's choice of John Brennan to lead the CIA appears to be less controversial than his decision to nominate former Sen. Chuck Hagel as secretary of defense.

The top Republican on the House intelligence committee, Rep. Mike Rogers, said in a statement Monday that he looks forward to working with Brennan at the CIA. Still, the Brennan nomination will raise questions about Obama's national security policy.

ROBERT SIEGEL, HOST:

Hugo Chavez has dominated Venezuela for so long that it's hard to imagine what the country would be like without him in charge. Opposition leaders are hoping for a new, more democratic system. But powerful factions in Venezuela want things to stay just as they are. Because the country is a key player in the region, NPR's Tom Gjelten says the U.S. is now making its own plans for life after Chavez.

U.S. officials say the satellite put into orbit by North Korea's rocket launch this week is wobbling, but that doesn't necessarily mean the launch itself was unsuccessful.

By the year 2030, for the first time in history, a majority of the world's population will be out of poverty. Middle classes will be the most important social and economic sector. Asia will enjoy the global power status it last had in the Middle Ages, while the 350-year rise of the West will be largely reversed. Global leadership may be shared, and the world is likely to be democratizing.

As President Obama and Capitol Hill lawmakers assess the need for spending cuts and tax increases against the risk of triggering a new recession, they might look across the Atlantic for insights from those who have already grappled with those budgetary questions.

The problem of excessive government debt has swamped economies across Europe and forced countries to take severe measures to cut their deficits. The first lesson from their "fiscal consolidation" experiences: It will hurt.

First, it was Egypt. At the height of the protest against the Mubarak regime in 2011, authorities shut the Internet down.

This week, it was Syria. Just as rebel forces there were making big gains, someone pulled the plug on the Internet, and Syria went dark.

Service was restored on Saturday, but Andrew McLaughlin, former White House adviser on technology policy, expects we'll see more of this.

In the Gaza Strip fighting, where a cease-fire was reached Wednesday, the Israeli military pounded Gaza with hundreds of airstrikes. Hamas, the militant Palestinian group that rules Gaza, launched hundreds of rocket attacks on Israel.

The weeklong battle temporarily diverted attention from Iran, the archenemy of Israel and a key ally of Hamas. Israeli leaders have threatened to strike Iran over its nuclear program.

Yet the Gaza fight may offer insights into what a possible confrontation between Israel and Iran would look like.

David Petraeus' resignation from the CIA further complicated the debate over the September attack on the U.S. mission in Benghazi, Libya.

Petraeus, a key figure in the events, stepped down as director after admitting to an extramarital affair. But members of Congress were so anxious to hear from him that they brought Petraeus back to Capitol Hill on Friday to get his version of the Benghazi story.

LINDA WERTHEIMER, HOST:

And I'm Linda Wertheimer. We've steadily been learning more about the people at the center of a military scandal. Retired general - and CIA director - David Petraeus resigned because of an affair.

INSKEEP: The affair was discovered when his mistress confronted another woman.

Officials in Washington are still trying to make sense of the sudden resignation last week of CIA Director David Petraeus. More details are emerging about the extramarital affair that brought Petraeus down. It came to light following an FBI investigation, which was not focused originally on the CIA director but soon led to him.

Gone from this year's presidential campaign are most mentions of climate change, environmental pollution, or green jobs. Former Gov. Mitt Romney, the GOP presidential nominee, prefers to call attention instead to the country's continuing dependence on foreign energy sources.

"I will set a national goal of North American energy independence by the year 2020," Romney declared in August.

The line is now a standard part of Romney's stump speech, and he repeated it in his first two debates with President Obama.
