Defense technologists are most successful when they hone in on specific problems. The Pentagon’s research agencies and their contractors were asked in 2003 to come up with ways to foil roadside bombs in Iraq and Afghanistan, and although they did not defeat the threat entirely, they did produce a number of useful detectors, jammers and other counter-explosive systems. More recently, military researchers received marching orders to help tackle the so-called “anti-access area-denial” threats, which is Pentagon-speak for enemy weapons that could be used to shoot down U.S. fighters and attack Navy ships.
The next wave of national security threats, however, might be more than the technology community can handle. They are complex, multidimensional problems against which no degree of U.S. technical superiority in stealth, fifth-generation air warfare or night-vision is likely to suffice.
The latest intelligence forecasts by the Obama administration and other sources point to five big challenges to U.S. and global security in the coming decades.
Biological Weapons: The White House published in 2009 a National Strategy for Countering Biological Threats with an underlying theme that biological weapons eventually will be used in a terrorist attack. To prevent deadly viruses from being turned into mass-casualty weapons, officials say, one of the most difficult challenges is obtaining timely and accurate insight on potential attacks. The Defense Threat Reduction Agency has a team of researchers working these problems. But they worry that the pace of research is too slow to keep up with would-be terrorists.
Nukes: Large stockpiles of nuclear weapons are tempting targets for nation-states or groups set on attacking the United States and its allies, officials assert. Black-market trade in sensitive nuclear materials is a particular concern for U.S. security agencies. “The prospect that al-Qaida or another terrorist organization might acquire a nuclear device represents an immediate and extreme threat to global security,” says an administration report. No high-tech sensors exist to help break up black markets, detect and intercept nuclear materials in transit and there are no financial tools to disrupt this dangerous trade. A much-hyped Department of Homeland Security effort to detect radioactive materials at U.S. ports has been plagued by technical hiccups. Analysts believe that although a full-up nuclear weapon would be nearly impossible for an al-Qaida like group to build, a more likely scenario would be a low-yield “dirty bomb” that could be made with just a few grams of radioactive material.
Cyber-Attacks: The drumbeats of cyberwarfare have been sounding for years. Network intrusions are widely viewed as one of the most serious potential national security, public safety and economic challenges. Technology, in this case, becomes a double-edge sword. “The very technologies that empower us to lead and create also empower individual criminal hackers, organized criminal groups, terrorist networks and other advanced nations to disrupt the critical infrastructure that is vital to our economy, commerce, public safety, and military,” the White House says.
The cybersecurity marketplace is flooded with products that promise quick fixes but it is becoming clear that the increasing persistence and sophistication of attacks will require solutions beyond the traditional.
Climate Change: The national security ramifications of climate change are severe, according to Defense Secretary Leon Panetta. While the topic of climate change has been hugely politicized, Panetta casts the issue as a serious security crisis. “In the 21st century, we recognize that climate change can impact national security — ranging from rising sea levels, to severe droughts, to the melting of the polar caps, to more frequent and devastating natural disasters that raise demand for humanitarian assistance and disaster relief,” Panetta said. The administration projects that the change wrought by a warming planet will lead to new conflicts over refugees and resources and catastrophic natural disasters, all of which would require increased U.S. military support and resources. The scientific community, in this area, cannot agree on what it will take to reverse this trend. There is agreement, though, that there is no silver bullet.
Transnational Crime: U.S. defense and law-enforcement agencies see transnational criminal networks as national security challenges. These groups cause instability and subvert government institutions through corruption, the administration says. “Transnational criminal organizations have accumulated unprecedented wealth and power through the drug trade, arms smuggling, human trafficking, and other illicit activities. … They extend their reach by forming alliances with terrorist organizations, government officials, and some state security services.” Even the United States’ sophisticated surveillance technology is not nearly enough to counter this threat, officials say.
