Economist and Nobel laureate Paul Krugman harshly criticized Defense Secretary Pete Hegseth and the Pentagon over their lack of direction and obsession with violence in the ongoing war with Iran. In a Substack post, Krugman accused Hegseth of relishing the thought of violence and called the administration's war plans 'deeply un-American' and 'horrifying'.

Why it matters

Krugman's criticism highlights growing concerns about the Pentagon's apparent 'lust for violence' and lack of a coherent strategy for resolving the conflict with Iran. As the war enters its 30th day, there are fears that the administration may escalate to a costly and destructive ground invasion without a clear path to victory.

The details

In his Substack post, Krugman took issue with Hegseth's focus on 'lethality' and his calls for 'overwhelming violence of action' against Iran. Krugman questioned how further military force would open the Strait of Hormuz or achieve the administration's objectives, arguing that the plans for a ground invasion of Iran were misguided and would likely result in a costly quagmire.

  • The Iran war has now entered its 30th day.
  • Talks of a potential ground invasion have emerged in recent days.

What they’re saying

“A month into the war, and now they're talking about pointless ground action and/or war crimes.”

— Paul Krugman, Economist and Nobel Laureate

“In this case, our Secretary of Defense, which is his legal title, although he calls himself the Secretary of War, continually argues that if only we get even more violent, if only we do even more damage, that this will somehow translate into success in Iran.”

— Paul Krugman, Economist and Nobel Laureate

“He clearly relishes the thought of violence himself. He's now holding prayer breakfasts, and in his prayer breakfast, he called upon the Lord to support us in 'overwhelming violence of action against those who deserve no mercy.'”

— Paul Krugman, Economist and Nobel Laureate

What’s next

It remains unclear whether any meaningful negotiations are actually underway between the U.S. and Iran, or what the administration's specific objectives are. However, the possibility of a costly and destructive ground invasion looms as the conflict drags on.

The takeaway

Krugman's scathing critique highlights the growing concerns about the Pentagon's apparent obsession with escalating military force in the Iran conflict, without a clear strategy for achieving a resolution. The economist's warnings about the potential for a disastrous quagmire underscore the need for a more thoughtful, diplomatic approach to the crisis.
