Trump destroys U.S. diplomacy and global trust in America

TEHRAN — From using negotiations as a pretext for surprise attacks to abducting and assassinating heads of state and reneging on American commitments, including his own, Trump’s damage to U.S. diplomacy will remain evident for many years to come.

One example is reflected in America’s close allies such as Canada and its trade war with the Trump administration, which has exploded over the past several days.

At a press conference, Canadian Prime Minister, Mark Carney said, “We’ve been under no illusions, we recognized from the start that America has changed. Our government understood before many that America would transform all of its commercial relationships, that it would put a series of tariffs on its closest allies and use economic integration as a weapon. We recognized that sometimes its signature was written in pencil.”

When asked by a journalist: “Why does it feel that Mark Carney is going to war?” the prime minister responded, “Because we were attacked.”

As the U.S.-Israeli aggression against Iran is in its sixth month, it is becoming clear to everyone except Trump’s most shameless loyalists and the most pro-war supporters of the Zionist regime that the war has been an undeniable failure.

It was an aggressive war that was supposed to ignite an armed insurgency. Instead, it rallied popular support around the Iranian government in defiance of the country’s oppressors, who have killed thousands of citizens and destroyed civilian infrastructure.

And a war launched to neutralize Israel’s primary adversary will likely make that adversary far stronger geopolitically than before, while driving American support for the regime to its lowest point.

In addition to wasting the lives of American soldiers in an unwarranted war launched on false pretenses, Trump’s blunder has depleted America’s arsenal and saddled the U.S. with roughly $100 billion more in debt. Meanwhile, the longer Trump delays the inevitable admission of defeat, the greater the risk of an economic catastrophe that could engulf not only America but the entire world.

According to American writer Brian McGlinchey, if this nightmare can be avoided, we will likely find that Trump has inflicted lasting damage to a critically important but intangible national asset: the ability of American diplomacy to engage constructively and effectively with its counterparts around the world.

Of course, this does not mean that the reputation of American foreign policy was spotless before Trump took office. It means that he and his team managed to drag it to extraordinarily low levels.

According to McGlinchey, Trump’s cooperation with the Israeli regime in waging an unjustified war against Iran represents one of the worst foreign policy decisions in the history of the American republic. But it is important to recognize that Trump laid the groundwork for the catastrophe of 2026 eight years earlier.

In May 2018, at the urging of then national security adviser John Bolton and Trump’s pro-Israel donors, Trump withdrew from the Iran nuclear deal.

Abandoning the nuclear deal and trust in America

The Iran nuclear deal was the culmination of two years of painstaking negotiations over highly technical provisions, conducted not only by representatives of the United States and Iran, but also by China, France, Germany, Russia, the United Kingdom, and the European Union.

Under the nuclear deal, Iran accepted significant restrictions on its nuclear energy program in exchange for the lifting of harsh economic sanctions. Among other provisions, the agreement required Iran to eliminate its stockpile of medium-enriched uranium, reduce its low-enriched uranium stockpile by 98 percent, cap future enrichment at 3.67 percent, accept additional international monitoring, and disable its heavy water reactor.

Responding to the demands of fervent Zionist supporters and Republicans eager to brand any Obama-era agreement as treason, Trump viciously attacked the Iran nuclear deal throughout his 2016 campaign, declaring that his “number one priority is to dismantle this disastrous deal with Iran.”

After appointing John Bolton as national security adviser in April 2018, an ardent advocate for war with Iran, he urged Trump to follow through on his pledge to scrap the deal, despite Iran’s full compliance with it.

At the time, Michael Malin at Queen’s University Belfast said: “Trump’s announcement that the United States will unilaterally withdraw from the nuclear deal with Iran is the most consequential foreign policy blunder yet from an administration that appears determined to undermine U.S. influence around the world. Trump’s move demonstrates that the United States cannot be trusted to keep its promises. It deepens the divide between the United States and its closest European allies. It will heighten tensions in an already smoldering Middle East”

After Trump withdrew from the agreement and reimposed the previous sanctions, Iran waited a full year before beginning to scale back its own commitments as stipulated in the terms of the deal.

After repeatedly denying that it was developing a nuclear weapon, a position that U.S. intelligence agencies repeatedly judged to be accurate, Iran returned to negotiations during Trump’s second term, once again prepared to give up its uranium stockpile.

In fact, less than 48 hours before the U.S.-Israeli aggression on February 28, Iran offered concessions that included diluting 60-percent enriched uranium, halting new enrichment for several years, capping future enrichment at around 20 percent, and expanding the scope of International Atomic Energy Agency oversight.

British National Security Adviser Jonathan Powell was struck by the strength of Iran’s offer, seeing it as a reason for hope that war could be avoided. But his hopes, and those of others, were about to be dashed.

The Trump administration's assault on diplomacy takes many forms, but nothing is more egregious than exploiting ongoing negotiations as a means to launch a surprise attack on a negotiating partner, including assassinating that country’s head of state. That is precisely what the Trump administration did to Iran on February 28, 2026.

Following the third round of talks in Geneva on February 26, the two sides had agreed to hold technical discussions the following week. Instead, in coordination with Benjamin Netanyahu, the Israeli Prime Minister and fugitive war criminal, Trump launched a full-scale war against Iran.

Turning negotiations into a “staged ruse”

U.S. Secretary of State Marco Rubio further damaged America’s credibility by attempting to portray the surprise attack as defensive. Rubio said: “We knew Israel was going to take some action, which would result in an attack on U.S. forces, and we knew that if we did not strike first before they launched those attacks, we would suffer greater losses.”

Observers quickly noted that Israeli dependence on Washington means that Trump effectively has veto power over any strike by the regime, rendering the rest of Rubio’s justifications hollow.

February was not the first time the Trump administration’s bad-faith diplomacy had deceived Iran in order to launch a surprise attack.

In June 2025, the administration completed five rounds of negotiations with Iran and scheduled a sixth for June 15.

On June 13, the Israeli regime launched an attack on Iran that Trump knew about in advance, boasting that the regime had informed him beforehand. On June 22, Trump joined the 12-day war imposed on Iran, striking Iran’s nuclear facilities.

Beyond the fact that surprise attacks are inherently unethical and illegal, launching them during negotiations undermines America’s long-term interests by fueling distrust among everyone who witnesses such a blatant betrayal.

After the full-scale war began on February 28, 2026, University of Washburn law Professor L. Ali Khan wrote about the consequences of turning negotiations into a “staged ruse”:

“Repeated breaches of good faith erode credibility and harm the nation’s goodwill. Goodwill is not a resource solely for weak nations; it also benefits powerful nations by enhancing their soft power. Now that the media is global in nature, the breach of good faith signals worldwide that it is pointless to make any deal with someone who would do the opposite after creating an expectation or reliance for the other party. Iran or any other state would be highly reluctant to trust the Trump administration again in future negotiations.”

Observers from around the world have noted that the international community must not assume global distrust will be so closely associated with Trump that it will disappear as soon as he leaves office. His administration already includes at least two potential successors, Marco Rubio and J.D. Vance, as well as senators, representatives, and governors who have cheered Trump’s disgraceful conduct and are inclined to imitate it.

And do not imagine for a moment that Democrats are immune to following damaging presidential precedents, regardless of what they say when a Republican president establishes them.
