Is US grand strategy dead? The political foundations of deep engagement after Donald Trump

International Relations scholars frequently warn that the American political system has become too fractured to sustain a coherent grand strategy. This perception generally rests on two premises: that President Donald Trump led an unprecedented assault on established principles of US foreign policy, and that Democrats and Republicans have become so polarized that they can no longer agree on a common vision for global leadership. By contrast, this article argues that the grand strategy of deep engagement retains robust bipartisan support. Even though President Trump rejected more expansive conceptions of liberal internationalism, his behaviour was largely consistent with deep engagement's principles. Moreover, when Trump departed from deep engagement-as with questioning the US commitment to NATO-his actions did not reflect voters' policy preferences. In fact, polling data indicate that public support for deep engagement is at least as strong today as it has been at any other point since the end of the Cold War. Altogether, the article thus demonstrates that the grand strategy of deep engagement is less embattled, and more politically viable, than the conventional wisdom suggests.
