When we face nature’s wrath, whether through earthquakes, wildfires, hurricanes or any other natural disaster, there is instantaneous solidarity among countries. Such solidarity and humanitarian support sometimes appear even between the worst of enemies. It might not last long in the face of geopolitical tensions, but it is proof that something deeper unites us. Today, Iran is facing a historic threat. It is not a military threat, but a lack of water and rainfall. Iran is living through its worst drought in more than 60 years.
