Former U.S. President Donald Trump said he believes any potential peace or nuclear agreement with Iran is effectively dead, adding that he no longer intends to negotiate with what he described as "sick people." His remarks come amid escalating tensions following renewed military exchanges involving Iran and the United States. Trump also warned that further attacks against U.S. interests could trigger additional military action. The comments indicate a significantly harder stance toward Tehran and suggest diplomatic engagement may remain unlikely unless conditions change substantially. Relations between Washington and Tehran have deteriorated in recent months as regional security concerns, sanctions and military operations continue affecting negotiations. International observers remain concerned that continued escalation could destabilize the Middle East and disrupt global energy markets. Oil traders are closely monitoring developments because increased conflict could threaten shipping routes and reduce energy supplies, potentially driving higher crude oil prices and increasing inflationary pressures worldwide. Despite the sharp rhetoric, diplomatic channels remain available through international intermediaries. Many governments continue urging restraint while encouraging renewed negotiations aimed at preventing broader regional conflict.
