The Pentagon must factor in major trends likely to shape the national security environment, including many that defy traditional military planning, Deputy Defense Secretary William J. Lynn III said here today.
The Defense Department must play a part in federal deficit-reduction efforts, Mr. Lynn said during the Center for Strategic and International Studies’ 2011 Global Security Forum.
“Since 9/11, we have had the ability to address new defense challenges with increased resources,” he said. “We will not have that luxury for the foreseeable future.”
The challenge, he added, is to manage the coming budget reductions wisely and responsibly, and apply resources so they can best meet future warfare trends.
Mr. Lynn cited the revolutionary changes that occurred during the last half-century alone, exemplified through the life of Frank Buckles, the last surviving U.S. World War I veteran, who died in February. Mr. Buckles saw the horrors of trench warfare during World War I, was rescued as a World War II prisoner-of-war just as the design for an atomic bomb was finalized, and lived to have his own Facebook page before he died at age 110.
The three revolutions that Mr. Buckles’ life encompassed — industrial, atomic and information — “brought an avalanche of military technologies and introduced whole new dimensions to war,” Mr. Lynn said. “The issue for us as we consider what capabilities and programs to protect in a defense drawdown is what course future technologies will take.”
Mr. Lynn identified three strategic trends he said are likely to shape the future U.S. national security environment: increasing access to lethality across the threat spectrum, longer-duration warfare, and the growing prevalence of asymmetric threats.
“They are each, in different ways, the result of our entry into a new era of war, one driven primarily by the overlay of the information age atop the industrial and atomic revolutions,” he said. “They can and they must inform our defense planning. What we need to do at this juncture, in this fiscal environment, is to take the long view about what strategic trends are important.”
Gone, Mr. Lynn said, are the days when the most economically developed countries possessed the most-lethal military power, and others had second-rate capabilities or little or no access to highly lethal technologies.
“Today, this linear relationship between economic and military power no longer holds,” he said. “Terrorist groups with few resources can mount devastating attacks. Insurgents can defeat our most advanced armor with fertilizer bombs. Rogue states seek nuclear weapons. Some criminal organizations even possess world-class cyber capabilities.”
This change has increased the risks the U.S. faces and broadens the range of threats it must be prepared to confront, he said.
“Defense planning must reflect this development,” Mr. Lynn said, ensuring the military has the capabilities to confront both high- and low-end threats.
“We have decisions about how to size our forces for these disparate contingencies, but we must equip for both,” he said. “In other words, we will need both fifth-generation fighters and counter-(improvised explosive device) technology.”
Current reality also challenges the long-held assumption that kinetic engagements would be relatively short, Mr. Lynn said.
Noting that operations in Iraq and Afghanistan have lasted longer than the U.S. participation in World War I and World War II combined, he said military planners must be prepared to sustain long-term commitments for a range of plausible conflicts.
Their planning, he added, must account for enough force structure to provide adequate troop dwell time between deployments.
“This is likely to have important implications for how we size, structure and utilize our reserve force components,” he said. “We need the ability to scale-up force structure for longer conflicts. The long-term costs of extended conflicts must be considered in our strategic calculus.”
Another trend Mr. Lynn said must be taken into account in posturing the military for the future is the increasing prevalence of asymmetric threats.
Recognizing that they can’t go up against the U.S. militarily, adversaries use asymmetric approaches that Mr. Lynn said “target our weaknesses and undercut our advantages.”
As a result, “insurgents such as the Taliban and al-Qaida in Iraq avoid engaging our military in direct force-on-force engagements,” he said. “Instead, they use IEDs and assassination as their weapons, and they hope to use the longer duration of war to wait us out.”
Traditional powers also seek asymmetric capabilities, increasingly turning to area-denial and anti-access tactics through the proliferation of precision-strike weapons, he said.
Sophisticated precision-strike technologies, once exclusive to the U.S. and its allies, will be available to more nations in the next 10 to 20 years, Mr. Lynn said.
This will have a cumulative effect that he said will challenge U.S. power-projection to distant parts of the world.
“To address these anti-access tactics and defeat area-denial strategies, we need to develop a range of capabilities, particularly missile defense and long-range strike,” Mr. Lynn said.
He cited major investments being made in a long-range strike system that will enable the U.S. to penetrate defenses and deliver munitions worldwide.
Mr. Lynn also cited the potential use of asymmetric tactics in cyberspace, a development he said that would threaten the Internet technology that increasingly underpins U.S. military and economic strength.
The cyber threat is maturing, Mr. Lynn said. Not only are its effects escalating, but more capabilities are being developed within terrorist groups which are hard to deter because they typically have few assets against which to strike back.
“If a terrorist group gains a disruptive and destructive capability, we have to assume they will strike with little hesitation,” he warned. “So in cyber, we have a window of opportunity to act before the most malicious actors acquire the most destructive technologies. We need to continue moving aggressively to protect our military, government and critical infrastructure networks.”
Looking to the future, Mr. Lynn said the challenge is to navigate current fiscal circumstances without disrupting the capabilities of the world’s most effective military force.
“We need to make the right judgments about the nature of our future security environment,” he said.
“We need to invest in the right capabilities and force structure that address the trends in warfare, … and we need to relentlessly adapt our technology and our doctrine as threats evolve and mature,” Mr. Lynn said. “If we do these things, we will ensure our forces are ready for the future of war.”
