IN HIS STATE of the Union address on Tuesday, President Bush worked himself into a lather about the dangers of "retreating within our borders." His speech bulged with ominous references to ostensibly resurgent isolationists hankering to "tie our hands" and leave "an assaulted world to fend for itself." Turning inward, the president cautioned, would provide "false comfort" because isolationism inevitably "ends in danger and decline."

But who exactly are these isolationists eager to pull up the drawbridges? What party do they control? What influential journals of opinion do they publish? Who are their leaders? Which foundations bankroll this isolationist cause?

Can America be America absent Wilsonian ideals? Perhaps not. But an America intoxicated with its self-assigned mission of salvation while disregarding prudential considerations will court exhaustion, both moral and material. Our present circumstances may not dictate a full retreat. But they do require a revived appreciation of what we can and cannot do.
