The United States remains committed to global primacy. That’s been a longstanding ambition that cuts across party lines inside the Beltway. Its security doctrines, diplomatic rhetoric and military posture continue to project the image of an indispensable nation whose umbrella guarantees the survival of allies from Europe to Asia. Yet beneath this facade, a widening gap has emerged between Washington’s strategic ambitions and its material capabilities.

America’s wounds are wholly self-inflicted, and it has only itself to blame. Many betrayals have been committed over the last two decades, including some against its own allies, undermining their trust.

It’s only a matter of time before the United States loses its predominant position as the controller of international rhetoric and is supplanted by China as allies and partners lose confidence.

Many analyses of the most recent American tariffs discuss the impact on China or China-US relations. But none discuss the reverse: how will such tariffs impact the US? What will the result of this impact mean on the future of American global leadership?

In recent years, the United States has failed to reshape world affairs to its liking as it once could. From its inability to oust Bashar Assad from Syria, to its unilateral revocation of the Iran nuclear deal, to its unsuccessful pressuring of allies to block Huawei, we see an America that has lost its touch on the global stage.

Economic clout shifting to emerging economies, combined with great power peace, have begun to challenge the United States’ alliance strategy: for many longtime allies, the military aspect of national interest no longer comes first.

The UN and China should fill the vacuum the US is leaving.

The US' strengths will help it retain global leadership - even after Trump's presidency.
