The U.S. expects a response from Iran within a few hours [3] as fighting in the Middle East continues for a second day [4].

This diplomatic tension persists despite a ceasefire in the region. The failure to reach an immediate agreement increases the risk of further escalation between the U.S. and Iran, potentially destabilizing the current fragile truce.

Secretary of State Marco Rubio has made several statements regarding the situation. According to YTN News, a response from Iran is expected by Friday [1]. The delay in communication has become a point of contention, as the initial window for a response was set at 48 hours [1], followed by a one-day extension [2].

Sung Il-kwang, a professor at Sogang University's Euro-MENA Research Institute, said the response continues to be delayed. He said that the timeline shifted from 48 hours to an additional day, yet no answer has arrived [1, 2].

U.S. officials are monitoring the situation closely following a recent White House speech by President Trump. Sung said that the content of that speech may contain important details regarding Iran [1]. The U.S. administration is now operating on a timeline of a few hours [3] to receive the necessary diplomatic feedback.

Combat has persisted for two days [4] despite the broader ceasefire efforts. The U.S. remains hopeful that the upcoming response will clarify Iran's position and potentially mitigate the ongoing clashes in the region.

The U.S. expects a response from Iran within a few hours.

The persistence of clashes during a ceasefire suggests a breakdown in local enforcement or a deliberate provocation. The U.S. strategy of setting strict deadlines—first 48 hours, then a one-day extension—indicates a high-pressure diplomatic approach intended to force a definitive stance from Tehran. If Iran fails to provide a satisfactory response within the current few-hour window, the U.S. may shift from diplomatic patience to more aggressive countermeasures.
