Dear voluntary blog visitor/helpless, compulsive addict: Happy New Year and all the best in 2005! For my first posting of this new year, a little something from the NYT about dominant civilizations that faded.

Author Jared Diamond concludes with this about the United States:

In this New Year, we Americans have our own painful reappraisals to face. Historically, we viewed the United States as a land of unlimited plenty, and so we practiced unrestrained consumerism, but that's no longer viable in a world of finite resources. We can't continue to deplete our own resources as well as those of much of the rest of the world.

Historically, oceans protected us from external threats; we stepped back from our isolationism only temporarily during the crises of two world wars. Now, technology and global interconnectedness have robbed us of our protection. In recent years, we have responded to foreign threats largely by seeking short-term military solutions at the last minute.

But how long can we keep this up? Though we are the richest nation on earth, there's simply no way we can afford (or muster the troops) to intervene in the dozens of countries where emerging threats lurk - particularly when each intervention these days can cost more than $100 billion and require more than 100,000 troops.

A genuine reappraisal would require us to recognize that it will be far less expensive and far more effective to address the underlying problems of public health, population and environment that ultimately cause threats to us to emerge in poor countries. In the past, we have regarded foreign aid as either charity or as buying support; now, it's an act of self-interest to preserve our own economy and protect American lives.
