The Biden administration defended Ukraine to protect democratic sovereignty, uphold the international rules-based order, and deter authoritarian aggression.

Strategic and Geopolitical Goals:

Deterring Aggression: Preventing unprovoked border changes by major powers to discourage similar actions globally, such as by China in the Indo-Pacific

Protecting Democracy: Safeguarding a sovereign, democratic nation from being overrun by an autocratic neighbor

Strengthening Alliances: Galvanizing NATO unity and expanding the alliance, which reinforced collective security in Europe.

Security and Defense Motivations:

Weakening a Threat: Degrading the conventional military capacity of Russia, a primary adversarial threat to U.S. and European security, without deploying direct American combat forces.

Escalation Management: Balancing robust military and economic aid with cautious restraint to prevent the conflict from triggering a direct U.S.-Russia confrontation or World War III.
