This article analyzes how Qatar strategically utilized its foreign policy to overcome the implications of the 2017 Gulf crisis. Using neoclassical realism, it investigates the ways in which Qatar used its foreign relations to mitigate the impact of a crisis that barred Qatar from aerial, naval, and land corridors in Saudi Arabia, Egypt, Bahrain, and the United Arab Emirates, henceforth referred to as the Quartet. The impacts are threefold. Starting from a macro-level perspective, Qatar leveraged its status as a crucial energy supplier, alongside the resultant financial boon, to prevent an international consensus supporting the claims of the Quartet. From a micro-level perspective, the likelihood of military escalation was circumvented by Qatar's ties with Turkey and the United States. Finally, the economic impact of the crisis was largely absorbed by Qatar's ties with Iran.The biblical story of David and Goliath presents a case in which the strategic use of resources can be effective in overcoming a larger threat.

While such an act was unprecedented, the source of discontent is not new. In fact, the crisis was an escalation of events in 2014 when the Quartet alliance cut diplomatic ties with QatarThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
