  • They begin the podcast debating whether the unfolding Israel–Hamas conflict will have the same level of strategic significance for Israel as the Yom Kippur War or the Six-Day War.
  • Tarrant, Thompson and Garman then discuss how the conflict has altered the balance of power in the Middle East, severing Iran’s crescent of influence by weakening Hamas and Hezbollah, coupled with the fall of Assad.
  • They wrap up the podcast examining what nations, if any, might assume the role of a security benefactor in the Middle East with a weakened Iran, and emerging open-source intelligence (OSINT) collection vectors.

Enjoy the podcast,
