What to read after Iran's Revolutionary Guard?

In "Iran's Revolutionary Guard", a thoroughly researched investigation of the IRGC, Steven O'Hern reveals new information about Hezbollah and IRGC operations inside America based on interviews with former and active members of the FBI, CIA, local law enforcement, military intelligence, and even one former Revolutionary Guard officer. O'Hern delivers a warning - the Revolutionary Guard is a danger to the well being of all U.S. citizens. For thirty years, Iran's Revolutionary Guard has conducted covert and overt military operations, built an economic empire, and has trained, financed, and guided terrorists to pursue one goal - the preservation and expansion of the Islamic revolution. Inside Iran, the IRGC controls or influences Iran's politics, economy, foreign policy, and directs its nuclear program. Outside of Iran, the operations of the IRGC and its proxies, including Hezbollah in Lebanon and Shiite militias in Iraq, have left a trail of death - from the 1983 truck bombing of U.S. peacekeepers in Beirut to numerous attacks on U.S. troops in Iraq and Afghanistan. No longer content to strike at U.S. troops in Iraq or at U.S. targets in other Persian Gulf countries, the IRGC is developing the capability to strike the continental United States and deliver a blow to the U. S. economy far worse than today's financial crisis. The author's research suggests that the IRGC may be planning to explode a nuclear weapon high above a midwestern city that would emit an electromagnetic pulse strong enough to render useless anything with a computer chip, including the hundreds of transformers that control the country's electrical grid.
