The American alliance with Europe will gradually weaken as both sides undergo profound demographic, cultural and ideological change.
The postwar Western alliance was not created by military interests alone. It rested on a shared political inheritance: classical liberalism, constitutional government, individual rights, national sovereignty and the intellectual legacy of the American and French revolutions. This common foundation enabled the United States and Western Europe to defeat fascism and later resist Soviet communism.
The alliance was never free of tension. Europeans often resented American power and dominance over global commerce, while Americans, especially since the creation of NATO, repeatedly complained that Europe was unwilling to pay for its own defense.
Yet today’s division is deeper. It is no longer only a dispute over budgets or strategy. Both Europe and the United States are struggling to integrate populations whose political and cultural assumptions may differ sharply from the liberal traditions on which the transatlantic alliance was built.
The difficulty is not immigration itself, nor the ethnicity of immigrants. The central question is whether newcomers, and the political institutions receiving them, continue to uphold the principles that made the Western alliance possible.
The growing skepticism toward Israel inside the United States may be an early symptom of the same process. America and Israel share an extraordinary amount of political, religious and historical heritage, yet increasingly powerful movements are attempting to portray the alliance as immoral, obsolete or oppressive.
Russia and China clearly benefit from the erosion of solidarity between America, Europe and Israel. Radical Islamist movements benefit as well. Each, for different reasons, seeks to weaken the cultural and strategic bonds holding the Western alliance together.
At the same time, white racial nationalism is not an answer. It is another destabilizing force, one that replaces a political civilization based on shared values with crude biological identity. It can be exploited by the same foreign powers that benefit from polarization and social collapse.
The West’s real weakness is not diversity, but the loss of confidence in its own principles. That crisis affects foreign policy directly. Societies that no longer believe they share a common civilization will eventually stop defending one another.
The campaign against Israel has become particularly effective because it exploits two historic Western vulnerabilities: guilt and antisemitism. The Palestinian cause is increasingly used not merely to criticize Israeli policy, but to delegitimize Israel, separate Jews from the Western political tradition and turn sympathy for the vulnerable into hostility toward the foundations of Western civilization itself.
The deepest danger, therefore, is not that America and Europe will formally abandon their alliances tomorrow. It is that the cultural meaning of those alliances will slowly disappear.
Once the shared civilization is gone, the treaties will become little more than paper.
