The breach of the Kakhovka Dam makes it clearer than ever: A rapid end to the war can only come through support for Ukraine's army. The reservoir contained 18 trillion liters of water, and when the dam broke, a catastrophic flood inundated parts of southern Ukraine, including the city of Kherson.

Tens of thousands of people are now without drinking water. Toxins are poisoning the environment and farming will be severely limited for the foreseeable future. The next several weeks are crucial. They will show whether Ukraine is able to expel the invading army.
