With his decision to pull some U.S. troops from Germany, his threats to draw down forces elsewhere in Europe and his downplaying of Iran¡¯s recent attacks on an important Gulf partner, President Donald Trump's latest moves foreshadow what could be the war's enduring legacy: the fraying of ties with key allies.

Even ?as the U.S. and Iran inch toward a potential off-ramp from their 10-week war, Trump¡¯s words and deeds have revived fears among Washington's long-standing friends ¡ª from Europe to the Middle East to the Indo-Pacific ¡ª that the United States might be unreliable in a future crisis.

In response, some traditional U.S. partners are starting to hedge their bets in ways that may bring long-lasting changes in relations with Washington, while adversaries such as China and Russia are looking to exploit strategic openings.
