A New Enemy Gains on the U.S.

By THOM SHANKER

WASHINGTON

POUND for pound and pounding for pounding, the Israeli military is one of the world’s finest. But Hezbollah, with the discipline and ferocity of its fighters and ability to field advanced weaponry, has taken Israel by surprise.

Now that surprise has rocketed back to Washington and across the American military.

United States officials worry that they’re not prepared, either, for Hezbollah’s style of warfare — a kind that pits finders against hiders and favors the hiders.

Certain that other terrorists are learning from Hezbollah’s successes, the United States is studying the conflict closely for lessons to apply to its own wars. Military planners suggest that the Pentagon take a page out of Hezbollah’s book about small-unit, agile operations as it battles insurgents and cells in Iraq and Afghanistan and plans for countering more cells and their state sponsors across the Middle East and in Africa, Southeast Asia and Latin America.
