In Biden’s foreign policy, friends and foes alike see echoes of the Trump administration.

At the annual gathering of United Nations world leaders this week, President Biden and Secretary of State Antony J. Blinken spoke ambitiously about international cooperation and a new diplomatic approach for a post-Trump America.

Mr. Biden’s speech at the UN on Tuesday portrayed an America whose withdrawal from Afghanistan had turned a page of 20 years of war after the attacks of September 11, 2001. Now, he said, states United are embarking on a new era of cooperative diplomacy to address global challenges, including climate change, the pandemic and the rise of authoritarianism.

The comments offered a great tribute to internationalism and a stark contrast to Mr. Trump’s non-diplomatic bluster. But the speech also came amid growing complaints that some of Mr. Biden’s signing policy measures echoed Mr. Trump’s approach.

French officials have openly compared the Biden administration to that of Mr. Trump in the recent failure to warn them of a strategic deal with Britain and Australia which they say forced them to pull out of the country. a sub contract, though Mr Biden eased strained relations to some extent in a meeting with President Emmanuel Macron on Wednesday. Mr. Blinken met his French counterpart in New York on Thursday.

The Paris conflagration might have been considered an isolated episode if it had not been for complaints from some NATO allies that Mr. Biden had withdrawn from Afghanistan without fully consulting them or alerting them to the Washington calendar. Mr. Trump was known to have surprised his longtime allies with impulsive or one-sided actions.

In a fiery speech at the United Nations General Assembly on Wednesday, Iranian President Ebrahim Raisi suggested that there was little difference between Mr. Biden and his predecessor, citing their respective foreign policy slogans: ‘or’ The ‘ America is back. ‘”

Loren DeJonge Schulman, who worked at the National Security Counsel and the Pentagon during the Obama administration, dismissed such parallels.

“It is absurd at first glance for allies, partners or anyone to think that there is continuity between Trump and Biden in terms of how they view allies, negotiate internationally, or approach national security,” a- she declared. “It’s a topic of discussion, and it’s a laughable topic.”

But even some of Mr. Biden’s allies admit what his enemies claim: that global concerns about whether Mr. Trump, or someone like him, could succeed Mr. Biden and reverse his efforts are valid.

In response to the ambitious targets proposed by Mr. Biden in his remarks to reduce global carbon emissions, an op-ed in the fierce Beijing newspaper Global Times raised a point all too familiar to Biden officials: “If the next US administration is a Republican again, the promises made by Biden will most likely be rescinded. “

The Iranians made the same point about Mr. Biden’s potential return to the 2015 nuclear deal that Mr. Trump abruptly left.
