We have entered an era, according to Greg Jaffe, of endless war:
In previous decades, the military and the American public viewed war as an aberration and peace as the norm.
Today, radical religious ideologies, new technologies and cheap, powerful weapons have catapulted the world into “a period of persistent conflict,” according to the Pentagon’s last major assessment of global security. “No one should harbor the illusion that the developed world can win this conflict in the near future,” the document concludes.
By this logic, America’s wars are unending and any talk of peace is quixotic or naive. The new view of war and peace has brought about far-reaching changes in agencies such as the CIA, which is increasingly shifting its focus from gathering intelligence to targeting and killing terrorists. Within the military the shift has reshaped Army bases, spurred the creation of new commands and changed what it means to be a warrior.
On the home front, the new thinking has altered long-held views about the effectiveness of military power and the likelihood that peace will ever prevail.
In the decades after Vietnam, the U.S. military was almost entirely focused on training for a big, unthinkable war with the Soviet Union. There were small conflicts, such as Grenada, Panama and the Persian Gulf War, but the United States was largely at peace.
After the Soviet collapse and America’s swift Gulf War victory, the military bet that it would be able to use big weapons and vastly better technology to bludgeon enemies into a speedy surrender. It envisioned a future of quick, decisive and overwhelming victories.
A decade of war in Iraq and Afghanistan has crushed the “smug certainties” of that earlier era, said Eliot Cohen, a military historian who served in the George W. Bush administration.
