Economist and Nobel Prize winner Paul Krugman criticized President Donald Trump's handling of foreign policy, particularly regarding the recent conflict involving Iran, during an interview on Greg Sargent's podcast.

Krugman argued that Trump's claims of success were not supported by the outcome of the conflict and contended that Iran emerged in a stronger position while the United States was weakened.

He described the resulting ceasefire arrangement as less effective than the nuclear agreement negotiated during the Obama administration, which Trump abandoned during his first term.Krugman also challenged Trump's economic claims.

He stated that job growth has been slower than during the final years of the Biden administration, unemployment has remained largely unchanged, and inflation has reduced real wage gains.

While acknowledging that stock markets have risen, he argued that the increase reflects a broader global trend rather than the direct result of Trump's policies.A central theme of Krugman's remarks was the long-term impact on U.S.international credibility.

He argued that allies and adversaries may increasingly question whether commitments made by the United States can be trusted, given that future administrations could reverse major agreements.According to Krugman, rebuilding the country's reputation could take decades of stable governance.

The economist was also critical of Trump's personal conduct, describing his social media posts as evidence of a leader seeking validation while being disconnected from the consequences of his policies.

As a symbolic example of what he views as administrative incompetence, Krugman cited problems with renovations to the National Mall's Reflecting Pool.Overall, he warned that the effects of policy mistakes and institutional damage could extend well beyond Trump's presidency.
