US tech billionaire Peter Thiel has cut ties with President Donald Trump, expressing deep skepticism and opposition to the unwarranted war on Iran.

Speaking at a lecture earlier this month, the German-born, US-based entrepreneur said the US government's military campaign raises doubts regarding the legality and wisdom of Trump's decision to launch an unprovoked war against the Islamic Republic.

Thiel said he was skeptical of the move and believes Trump should never have launched it, according to a Politico report on Wednesday.

“I’m skeptical of [the war], I think we should not have done it,” Thiel said. “There were a lot of mistakes that were made.”

The tech guru, who maintains well-established connections to some of the most recognized figures in the global elite, US policymakers, and top tech innovators, admitted he wasn't confident the Trump administration had the hardware and software needed to sustain a war on Iran.

“Maybe we don’t have the hard power," Thiel added. "Maybe we’re going to lose the soft power war.”

Trump approval rating falls to record low ahead of US midterms

Trump’s approval rating has fallen to a record low of 32%, according to a Reuters/Ipsos poll, as Republicans face growing voter concerns ahead of the US midterm elections.

Thiel's inner circle includes figures who have founded or developed major tech companies—including PayPal, Facebook, LinkedIn, Palantir Technologies, SpaceX, Affirm, Slide, Kiva, YouTube, Yelp, and Yammer—featuring familiar names such as Elon Musk, Mark Zuckerberg, and dozens of other industry titans.

The prominent tech billionaire's comments indicate that a faction of major Republican donors is increasingly at odds with the unpopular president over one of his defining foreign policy and military decisions: the war on Iran.

Delivered on October 12 at a private event, these remarks represent Thiel's most explicit public criticism of the unpopular war, coming with just weeks left until the midterm elections, where the Republicans' chances of retaining majority control of Congress appear increasingly slim.

Meanwhile, Trump's overall popularity remains on the decline.

The drop in Trump’s approval ratings is directly linked to Americans' growing concern over how the war on Iran is impacting the cost of living. The US aggression has triggered soaring fuel prices, contributing to increased daily hardships for the American working class.

The US and Israeli forces launched the ongoing aggression against Iran on February 28. Since then, key US military facilities in the region—including installations in Qatar, Bahrain, Saudi Arabia, and Jordan—have come under retaliatory attacks by the Iranian Armed Forces, dealing a heavy strategic and political blow to the Trump administration.
