Our Mission

Ukraine’s defense operations are setting new standards in modern military practice.

Every domain of contemporary conflict — air and missile defense, drone warfare, electronic and cyber operations, battlefield logistics, and multi-national coordination, is transformed in Ukraine.

This war extends beyond Ukraine’s borders, carrying worldwide strategic implications.

SII exists to ensure the lessons, innovations, and institutional shifts forged in Ukraine inform and strengthen the broader security architecture shared by the United States, NATO, and other democratic allies.

Snake Island, in the Black Sea, commands key maritime routes linking Europe, the Middle East, and the Caucasus. In 2022, when Ukrainian forces refused to surrender there to russian invaders, Snake Island became a global symbol of strength, defiance, and democratic resolve.

Snake Island also sits at the crossroads of vital trade corridors — a gateway between regions and a pivot point for security in the wider Black Sea.

Just as Snake Island connects key geographies, SII aligns frontline innovation with global security priorities — turning a moment of defiance into a platform for U.S.-Ukraine long-term security partnerships.

Snake Island – the strategic symbol:

Our team brings together Western-educated professionals and Ukrainian veterans — uniting Western strategic thinking with firsthand experience of war.

SII was established in 2024 to strengthen Ukraine–U.S. defense and security relations.

FOUNDATION

Forge a Ukraine-rooted international security ecosystem to convert battlefield-proven expertise into shared standards, training, joint programs, and policies that fortify the free world.

OUR GOAL

Advance Ukraine in the West by building and scaling strategic security cooperation — convening trusted partners across government, industry, and civil society.
