If either side (US/Iran) officially stop the ceasefire it's a NO
If we get to the two weeks and get an extension of the ceasefire between (US/Iran), or a peace deal it's a YES

If Israel continue it's offensive on Lebanon I will not consider it as an end to the ceasefire by itself.

If hostilities between Iran and Israel start over but the ceasefire continue between US and Iran, it's a YES
