Ukraine's Post-Soviet Path
How Ukraine navigated independence, nuclear disarmament, and the struggle between European and Russian orientations.
Independence and the Nuclear Question
When Ukraine declared independence in August 1991, confirmed by a December referendum in which 92% voted to leave the Soviet Union, it inherited the world's third-largest nuclear arsenal — roughly 1,900 strategic warheads deployed on its territory. Ukraine also possessed significant conventional military assets, a large population of 52 million, and substantial industrial and agricultural capacity. On paper, it had the potential to become a major European power.
The nuclear question dominated Ukraine's early diplomacy. The United States and Russia both pressured Ukraine to give up its nuclear weapons, arguing that multiple successor states with nuclear arsenals would destabilize the global nonproliferation regime. Ukrainian nationalists argued that the weapons were the country's ultimate security guarantee against Russian aggression. They would prove tragically prescient.
In 1994, Ukraine signed the Budapest Memorandum, transferring its nuclear warheads to Russia in exchange for security assurances from Russia, the United States, and the United Kingdom. The three guarantors committed to respect Ukraine's sovereignty, independence, and territorial integrity, and to refrain from the threat or use of force against it. The memorandum was not a legally binding treaty — a distinction that would matter enormously twenty years later.
