The cause of imperialism, weakened for a time by the fall of the European and Soviet empires, has found new advocates. The fact that the 21st century imperial power happens to be the United States of America, whose independence from colonialism was declared 228 years ago, seems not to matter. The neoconservatives’ project to position the United States as the world’s dominant power — and to use that power to govern in venues chosen seemingly by them alone, and collectively where reasonably easy but unilaterally where necessary — has been advanced and saluted.
