Is the US-Iran ceasefire already doomed?

Expectations for the talks between the US and Iran in Islamabad are modest, with a risk that the meeting may not occur. Tehran's reaction is ambivalent, with the government portraying the ceasefire as a victory, while some warn it may weaken Iran's deterrent posture. The negotiations will proceed based on Tehran's 10-point proposal, reflecting Iran's terms more than those of the US.
