Nance 2networks. Nations are now sharing terrorist-related information and interacting with security agencies around the world, which requires effective communication dialogue. International dialogue must be a strategic requirement for protecting the homelands.On a national level, to ensure a homeland that is safe, secure, and resilient against terrorism, the United States Department of Homeland Security established the 2010 Quadrennial Homeland Security Review (QHSR) to serve as a guide for homeland security activities.

For example, Russia stockpile, and the emergence of new risks like Pakistan, and Iran.

On July 13, 2005, based upon his findings, Secretary Chertoff announced a six-point agenda, which included a significant reorganization of the department (dhs.gov).
