The shadowy realm of international intelligence is governed not by formal treaties but by a delicate web of unspoken agreements, strategic necessities, and calculated risks. These informal rules help prevent chaos among allies while allowing agencies to pursue national interests. Former CIA covert intelligence officer Andrew Bustamante has offered candid perspectives on these dynamics, drawing from his operational experience and public discussions. Key elements include the U.S. restraint toward Israel, the no-spy pact within the Five Eyes alliance, contrasting operational styles between American and British services, and the inherently contradictory nature of global partnerships.
Why the CIA Is Effectively Barred from Spying on Israel
One of the most tightly held arrangements in U.S. intelligence involves Israel. Historical records indicate that as early as 1951, the CIA and Israel’s Mossad established a secret understanding not to conduct espionage against each other. This pact, facilitated in part by figures like CIA counterintelligence chief James Jesus Angleton, aimed to foster close cooperation amid shared threats during the Cold War.
The rationale remains pragmatic: the political blowback from any discovered U.S. spying on Israel would be catastrophic. Given the deep strategic alliance—bolstered by substantial U.S. military aid, training, and diplomatic support—such an incident could fracture bilateral ties and trigger severe domestic and international repercussions. Bustamante has described Israel as a vital “first wall of defense” for American interests in the Middle East, providing frontline intelligence on threats like Iran, Hezbollah, and Hamas. In return, the U.S. benefits from Israel’s aggressive posture and capabilities, often handling operations that align with shared goals.
Yet the relationship is not without tension. Despite the agreement, Israel has been implicated in espionage activities on U.S. soil, including economic and technological theft, as noted in various declassified reports and incidents like the 1985 Jonathan Pollard case. Trust is selective, with both sides sharing intelligence judiciously while maintaining vigilance. The arrangement persists because mutual benefit outweighs the risks of violation.
The Five Eyes Alliance: Mutual Restraint Among Trusted Partners
At the heart of Western intelligence cooperation lies the Five Eyes (FVEY) network, comprising the United States, United Kingdom, Canada, Australia, and New Zealand. Rooted in the 1946 UKUSA Agreement and post-World War II code-breaking collaboration, this alliance enables unparalleled sharing of signals intelligence, surveillance, and threat assessments.
A fundamental unspoken rule: members do not spy on one another. This restraint is built on deep trust among like-minded democracies, allowing them to operate as a unified force against adversaries such as China, Russia, and Iran. Bustamante has highlighted how this “fused spy machine” maximizes collective strengths while avoiding internal friction. Breaches are exceptionally rare, as the strategic value of seamless cooperation far exceeds any short-term gains from targeting partners.
While not formally part of Five Eyes, Israel has developed informal ties with the alliance, particularly in shared operations against common threats, further illustrating how alliances evolve through necessity.
American Scale Versus British Speed: A Complementary Trade-Off
Espionage agencies reflect their nations’ characteristics, and the contrast between U.S. and UK operations exemplifies this. The United States, through the CIA and NSA, commands immense scale—massive budgets, global technological infrastructure, and vast resources for surveillance, cyber operations, and human intelligence networks.
This breadth enables unparalleled reach but comes with bureaucratic hurdles: multiple layers of approval slow decision-making and execution. In contrast, British services like MI6 and GCHQ prioritize agility and speed, operating with leaner structures that allow rapid deployment and adaptation in dynamic environments.
Bustamante has noted this trade-off as a strength within Five Eyes: America’s resources provide the heavy lifting, while Britain’s nimbleness enables swift, targeted actions. Together, they create a balanced, effective partnership.
The Contradictory Nature of Intelligence Relationships
Global espionage is full of paradoxes—allies cooperate intensely yet harbor suspicions, share secrets selectively, and occasionally clash. The U.S.-Israel dynamic is a prime example: a no-spy understanding coexists with historical frictions, yet collaboration endures in critical areas.
Sensitive joint missions highlight this complexity. Operations like the Stuxnet cyber campaign against Iran’s nuclear program—widely attributed to U.S.-Israeli cooperation—demonstrate how shared objectives can override differences. Such efforts disrupt threats without overt military action, showcasing intelligence as a tool for strategic advantage.
These relationships are fragile, reliant on perceived mutual benefit and the avoidance of unacceptable risks. As Bustamante has observed, Israel frequently acts in ways that indirectly benefit broader Western interests, even as underlying contradictions persist.
In the end, the unspoken rules of espionage exist to manage an inherently unstable landscape. They reflect not idealism but cold calculation: in a world of perpetual threats, restraint among allies and selective partnerships are essential for survival and dominance.
