Trump’s Diplomatic Week Reveals Limits of US Power Abroad
Donald Trump spent the week trying to show that the United States remains powerful around the world.
He spoke strongly at the United Nations and threatened Iran.
He also met Chinese leader Xi Jinping to discuss trade, technology and other difficult issues.
The meeting produced only a short extension of a trade truce.
The war with Iran has lasted nearly seven months and has pushed up energy prices.
Many US allies do not want to help with the war because Trump began it without consulting them.
Other countries have also resisted his positions on Ukraine, Russia and Greenland.
Critics say these events show that Trump cannot always make other countries do what he wants.
The White House says his foreign policy is producing results and advancing US interests.
Donald Trump’s UN speech projected military and economic strength while threatening Iran and defending pressure on Venezuela.
His summit with Chinese President Xi Jinping produced little beyond a two-month extension of an existing trade truce.
The nearly seven-month Iran war has raised energy prices, disrupted shipping and become a major political liability for Trump.
Allies and other world leaders have increasingly resisted Trump’s demands on Iran, Ukraine, Russia and Greenland.
Trump’s foreign-policy challenges come as Republicans face November midterm elections that could reduce his political leverage.

Critics and Resisting Governments

Strength of Trump’s foreign policy
Critics and Resisting Governments
Critics argue that resistance from allies, China, Iran, Russia and others shows Trump’s influence is weakening and his agenda has stalled.
Trump Administration
The White House rejects that assessment, saying Trump is focused on results rather than posturing and has advanced US interests.
Approach to Iran
Critics and Resisting Governments
Opponents say the war is unpopular, has raised energy costs, divided Trump’s political base and failed to force Iran to yield.
Trump Administration
Trump defended the attack at the United Nations and said it helped prevent Iran from obtaining a nuclear weapon.
Relations with China
Critics and Resisting Governments
Critics say Trump adopted a notably less confrontational posture toward Xi because China controls rare-earth minerals important to technology and vehicle manufacturing.
