It also affects how we and our politicians view such operations. President Obama’s decision to send a small, brave Navy Seal team into Pakistan for 40 minutes was described by one of his advisers as “the gutsiest call of any president in recent history.” Yet few even talk about the decision to carry out more than 300 drone strikes in the very same country.

I do not condemn these strikes; I support most of them. What troubles me, though, is how a new technology is short-circuiting the decision-making process for what used to be the most important choice a democracy could make. Something that would have previously been viewed as a war is simply not being treated like a war.

THE change is not limited to covert action. Last spring, America launched airstrikes on Libya as part of a NATO operation to prevent Col. Muammar el-Qaddafi’s government from massacring civilians. In late March, the White House announced that the American military was handing over combat operations to its European partners and would thereafter play only a supporting role.

The distinction was crucial. The operation’s goals quickly evolved from a limited humanitarian intervention into an air war supporting local insurgents’ efforts at regime change. But it had limited public support and no Congressional approval.

When the administration was asked to explain why continuing military action would not be a violation of the War Powers Resolution — a Vietnam-era law that requires notifying Congress of military operations within 48 hours and getting its authorization after 60 days — the White House argued that American operations did not “involve the presence of U.S. ground troops, U.S. casualties or a serious threat thereof.” But they did involve something we used to think of as war: blowing up stuff, lots of it.

Starting on April 23, American unmanned systems were deployed over Libya. For the next six months, they carried out at least 146 strikes on their own. They also identified and pinpointed the targets for most of NATO’s manned strike jets. This unmanned operation lasted well past the 60-day deadline of the War Powers Resolution, extending to the very last airstrike that hit Colonel Qaddafi’s convoy on Oct. 20 and led to his death.

Choosing to make the operation unmanned proved critical to initiating it without Congressional authorization and continuing it with minimal public support. On June 21, when NATO’s air war was lagging, an American Navy helicopter was shot down by pro-Qaddafi forces. This previously would have been a disaster, with the risk of an American aircrew being captured or even killed. But the downed helicopter was an unmanned Fire Scout, and the story didn’t even make the newspapers the next day.
