How might the Iran situation develop?

US President Donald Trump has extended the two-week US-Iran ceasefire which is set to expire on April 22, saying it will last until Tehran submits a proposal to end the conflict. But at the same time, Washington is maintaining its blockade on Iranian ports, keeping pressure firmly in place. Iran has pushed back hard, calling the blockade an "act of war" and a violation of the ceasefire itself. Meanwhile, talks remain uncertain, with both sides signaling deep mistrust. So what does this truce really mean? Is this a step toward peace, or a pause before the next escalation?
