Against All Enemies by Tom Clancy

Working behind the scenes for the CIA, ex-Navy SEAL Maxwell Moore arrives at a rendezvous to take charge of a high-ranking Taliban captive and barely escapes with his life. Undaunted, Moore is relentless in his quest to find the terrorist cell responsible, but what he discovers leads him to a much darker conspiracy in an unexpected part of the globe...

After years of planning, the Taliban have come to terms with a vicious Mexican drug cartel and agreed to supply them with opium. For the cartel, the deal means money, power, and ultimate control of the drug trade. But for the Taliban, it is a long awaited opportunity: to exploit the cartels and bring the fire of the jihad to the hearts of the infidels, striking against the very heart of America.
