Pakistan has the best chance to conquer Jerusalem. Israel is wounded. Iran is keeping it engaged. Arab countries are with Pakistan.
Before the US and Iran reach a peace agreement and a ceasefire, Pakistan should attack immediately. In the picture, you can see the range of Pakistani missiles. When Iran rains missiles on one side and Pakistan rains missiles on the other, Israel will be finished in a few hours. Iran's missiles and drones are blocking the defense systems installed in Arab countries.
They will not stop Pakistan's missiles because they have no problem with Pakistan. So, they should use the air force to halve it and then use the land army. They do not have that much land army. In two days, the flag of victory can be planted in Jerusalem.
