The United States is the essential nation. We rally allies and partners to stand up to aggressors and make progress toward a brighter, more peaceful future. The world looks to us to solve the problems of our time. That is the duty of leadership, and America will lead. For if we walk away from the challenges of today, the risk of conflict could spread, and the costs to address them will only rise.

Biden referred to the historical experience of two world wars, warning that the crisis does not burn itself out when aggression in Europe goes unanswered. It draws America in directly.

That’s why our commitment to Ukraine today is an investment in our own security. It prevents a broader conflict tomorrow… We are keeping American troops out of this war by supporting the brave Ukrainians defending their freedom and homeland,” Biden stressed.
