In 1973, Arthur Schlesinger wrote about the tendency in American history for the president to assume sweeping powers in times of war and crisis. The balance of power established by the Constitution gets upended; Congress and the courts take a back seat; and the executive makes decisions about life and death largely unchecked. He called this “the imperial presidency.” Today, with President Obama turning to Congress to endorse a military strike on Syria, the imperial presidency is beginning to wane.

It’s about time. The 1990s seemed to presage a return to a more balanced government, with Cold War defense spending slashed and “the peace dividend” contributing to a more balanced budget. But then 9/11 happened; America launched a war on terror; and the rest, as they say, is history.

The imperial presidency has some justification in times of acute peril. The immediate aftermath of 9/11 certainly justified some degree of unilateral executive action, as did in its way the financial crisis in the fall of 2008. And few would argue that at times of all-out war, with the country fully mobilized to fight a genuine threat such as Germany and Japan during World War Two, ceding powers to the executive branch is imperative.

But it is equally vital to pare those back when they are no longer required — though this is easier said than done. People do not cede power easily, and bureaucracies are far easier to construct than dismantle. The war on terror has been conducted by an assertive executive branch and a compliant Congress and judiciary. Defenders will say that that’s a good thing, and a necessary one to keep the country safe. Either way, it tilts the balance toward the imperial presidency.

It’s a sign of just how far down the imperial path we’ve gone that Obama’s decision to look for Congressional authorization before sending missiles into Syria was greeted with surprise and not a little contempt. The decision, apparently made over the weekend before Labor Day, caught even Obama’s aides unawares. And rather than hailing the decision as a sign of respect for the congressional war making power specified by the Constitution, a fair number of commentators and even congressional representatives decried the move. Rep. Peter King (R-NY) denounced the decision in blunt language: “his failure to act was a woeful abdication of the president’s powers as commander-in-chief and sent the entirely wrong signal to an increasingly dangerous world.”
