In Star Wars III: Revenge of the Sith, when Chancellor Palpatine transforms the republic into an empire, Senator Amidala remarks:

So this is how liberty dies … with thunderous applause.

But it can also happen in silent acquiescence. For decades now, successive Congresses have evaded their responsibility to make decisions about the deployment of U.S. armed forces abroad. I write about the latest instance of this, in Libya, in today’s Britannica column:

Presidents have an obligation to obey the Constitution and the law. But one of the ways that separation of powers works is that each branch of government is supposed to jealously guard its prerogatives from usurpation by the other branches. Too often Congress ducks that responsibility, preferring to let presidents make decisions, make law, and make war without the involvement of Congress. As Arthur M. Schlesinger, Jr., explained in his book The Imperial Presidency, the expansion of presidential war-making power has been “as much a matter of congressional abdication as of presidential usurpation.”

The president is derelict in his duty to obey the Constitution and the War Powers Resolution. And Congress is derelict in its duty to assert its constitutional authority. And I’m still wondering what’s happened to the antiwar movement, which ought to be loudly protesting not just the continuing wars in Iraq and Afghanistan but the newborn war in Libya.

As George Will said last week, “even if you think the War Powers Resolution is an unwise law—it is a law.” And a former law professor who is now the president of the United States should obey the law. Will expanded on that point in his Sunday column, titled “Obama’s Illegal War,” in the old-fashioned print edition of the Washington Post.
