Hizbullah’s capture of American spies has severely crippled the U.S. war on the terror group that is responsible for more American casualties than any other group in the past 10 years.

Hizbullah leader Hassan Nasrallah this summer proudly stated that the terrorist organization and political party caught at least two American spies who had infiltrated into Hizbullah. American media reported Monday that Hizbullah has nabbed a dozen spies, whose fate is unknown.

The damage to intelligence has been especially high, according to current and former officials interviewed by the Associated Press. Officials said that one of the reasons has been the Bush and Obama administrations’ rush to kill terrorist leaders, taking the emphasis off of spy networks.

One deadly result was the killing of seven CIA workers and the wounding of six others in a suicide bombing in Afghanistan two years ago. The terrorist had posed as in informant.

It is known that Israel and the United States share intelligence at the highest levels, and Lebanon’s capture of alleged spies for Israel has made things even tough in the war on terror in Lebanon. Hizbullah and pro-Syrian parties dominate the Beirut government, which is part of the Iranian-Hamas axis.

The U.S. State Department has termed Hizbullah as “the most technically capable terrorist group in the world.”

Its alliance with Iran gives both Hizbullah and the Islamic Republic shared intelligence and technology, such as identifying mobile phones used by spies.
