The US administration has officially rejected the latest Iranian proposal aimed at de-escalation, passed through mediating diplomatic channels, deeming it insufficient and falling short of the understandings required for a comprehensive agreement. High-ranking US sources confirmed that the offer contained no substantial progress, stressing the necessity for Tehran to make a swift and radical shift in its negotiating stance. Using explicitly escalatory language, Washington hinted that continued Iranian intransigence might force the US administration to abandon the diplomatic track and resort to military solutions. In the same context, Washington categorically denied circulating reports about its agreement to partially lift economic sanctions in exchange for halting the escalation. These developments occur as bilateral relations face one of their worst crises, amid strenuous international and regional efforts to contain the situation and prevent a descent into a full-scale war that could have catastrophic repercussions for Middle East security and the stability of global energy markets.
