Once you see this film you will want to become a lifetime patron for St. Jude’s Children’s Hospital. In Declaration of War, watching the trauma and terror of having a child with cancer may compel you to want to fight against childhood cancer with a vengeance. Cancer is a ridiculously democratic malignancy. It will strike anyone regardless of age, gender, class, income, popularity, etc. Cancer has no mercy nor does it play favorites. Once it has chosen someone, even a child, it wrecks emotional havoc on everyone affected.
