Our Story

The gate keeper of Israel's national security & resilience & social cohesion


Atchalta is a non-partisan, Zionist non-profit organization dedicated to being the guardians of national security, resilience, and social cohesion in Israel.

Structured as both a think tank and an action-oriented entity, Atchalta generates innovative knowledge while actively ensuring the practical implementation of its ideas and solutions. We support both formal and informal leaders within Israel and the broader Jewish community.

Our core competency lies in the creation of new knowledge for tangible impact. Drawing on Zvi Lanir's Strategic Surprise theory, our approach is designed to reveal overlooked blind spots and challenge prevailing misconceptions, potentially catching Israeli and Jewish leadership off guard globally.

Such blind spots are present within accessible knowledge domains, yet are often disregarded or filtered out due to their incongruence with our established worldview. Our methodology excels at detecting and articulating this implicit knowledge.

Our methodology employs mind mapping software and generative AI language models to meticulously analyze reality. This process allows us to delineate current reality perceptions, uncover hidden insights, identify inherent biases, and devise strategic responses.


Subsequently, we strive to actualize our solutions and insights through direct engagement with Israeli and Jewish leaders, alongside efforts in public affairs, community engagement, education, marketing, training, and coalition-building.
