First of all the Imam is very luckily that the Gazan jihadis did not complete they operation of Flooding-Out Al-Aqsa Mosque. In addtion, lucky that the beautiful mosque had not been hit by Howling Hooter missiles, erratic Gazan rockets and even the directionless drones of the Hizzybillies.
Secondly, the Imam cannot speak for all Palestinians. Each Palestinian once weened off the UN addictive refugee funds, will have a choice when and where to go. Hopefully many will stay to help the Palestinian economy prosper, but many will also decide to try their luck in other parts of the world. Those more prone to jihadism and holy-roller warring, will probably move to Turkiye, Qatar, Algeria, South Africa, Espana and Eire. Others will try the more adventurous nations.
