American liberalism is an offshoot of European leftism, and European leftism is a 20th-century reaction to European hegemony over the past five centuries. European leftism sprung from the embers of a dying empire; Britain's self-loathing and breast-beating over its colonialist history only became an issue after British power had dissipated. Self-flagellation is a luxury only empires of the past can afford; it is also a useful tactic for past empires now fearing retaliation. More than anything, however, the Europeans rely on the strength of America to protect them against their past discretions. They can apologize for their ideals without consequence, since America will shield them from their Third World-assisted suicide. Europe can retreat to the international Green Acres Retirement Community and murmur softly over its bloody hands. America will foot the bill.
The American left wishes to practice the post-hegemonic multiculturalism of the Europeans and skip over the centuries of empire, which it sees as inherently exploitative and evil. This ignores three crucial facts. First, European multiculturalism is inherently flawed. Europe's colonialist history does not excuse the evils of other cultures, nor does it negate Europe's legacy of reason and liberty, which came to fruition in America. Second, America has no choice in the matter of empire; we cannot decline the honor. Doing so would entail abandoning our economic system and our Judeo-Christian values -- ourraison d'etre . Third, no one will pay for our Green Acres retirement package. There is no global community willing to allow countries to live peacefully on their pensions. A weak country in the absence of a protector is a country on the verge of extinction. America has no protector. The Europeans are content in their decadence. We and we alone are the last pillar of Western civilization.
America is not an empire of the past. It is today's empire, and it is far stronger than any empire in modern history. America cannot rely on any other empire to protect it; it must protect itself. And America cannot maintain its global status if the American left insists on viewing America as just another country, no better and sometimes worse than any other. America cannot maintain her power, and by extension her safety, if the American left spends its time pushing for America to apologize for its own principles.
