Who could? The UN, the UK, Germany, France, the US, Israel, the Red Cross, the Red Crescent, Italy, the Saudis, Turkey, Quatar, Iran, Russia, Iraq, etc. - all could help easily, within hours. Who will step up today?
All they need is water, food, tents, shovels, and maybe some machine guns air-dropped to them prevent a Biblical-style genocide. Where is everybody? On vacation?
