If you think about it - just how many highly sophisticated al-Qa’eda underground bunker complexes have they found in Afghanistan ?

None.

Why ? There bever was any.
Tora Bora?

And what about this

HIGH-RENT CAVES

Osama did some building for the infidels in Afghanistan as well. That was during the late 1980s. Under contract with the CIA, he and the family company built the multi-billion dollar "caves" (1) in which he is now, supposedly, hiding, thus causing the U.S. and Britain to bomb the Red Cross, the Red Crescent, and other strategic military installations:

"He brought in engineers from his father's company and heavy construction equipment to build roads and warehouses for the Mujaheddin. In 1986, he helped build a CIA-financed tunnel complex, to serve as a major arms storage depot, training facility and medical center for the Mujaheddin, deep under the mountains close to the Pakistan border."
