That would further destabilise global energy markets, increase inflation and apply additional pressure on Trump to halt attacks.\n\nThe war is deeply unpopular in the US and has inflicted economic harm on Americans.\n\nThe MoU mediated by Qatar and Pakistan and signed last month aimed to create the conditions to bring the war to a permanent end.\n\nHowever, Tehran and Washington have since declared the accord “over” after accusing each other of violating it.","source_name":"Al Jazeera","source_url":"https://www.aljazeera.com/news/2026/7/18/iran-supreme-leader-warns-of-unforgettable-lessons-if-us-attacks-continue?traffic_source=rss","url":"https://www.aljazeera.com/news/2026/7/18/iran-supreme-leader-warns-of-unforgettable-lessons-if-us-attacks-continue?traffic_source=rss","author":"Unknown Author","author_name":"Unknown Author","published_at":"2026-07-18T18:55:05.000Z","publication_date":"2026-07-18T18:55:05.000Z","image_url":"https://www.aljazeera.com/wp-content/uploads/2026/07/afp_6a5bbf5ec42e-1784397662.jpg?resize=770%2C513&quality=80","category":"world","topic":"world","tags":[],"political_bias":null,"bias_score":null,"confidence_score":null,"credibility_score":null,"factual_quality":null,"reading_time":3,"word_count":554,"view_count":0,"breaking":false,"breaking_news":false,"ai_analysis":null,"fact_check_status":"unverified","archive_status":"hot"}}
