The values that beat in the hearts of the fallen are the secret to the strength of the Israel Defense Force to this very day. The IDF spirit is the common language shared by those who serve."Eisenkot called on soldiers to lend a hand to the bereaved families of the fallen, writing that "in their death, the fallen have charged us with one more thing: To stand by their families and accompany them on the journey of life after loss, a journey that began on the day the light of their life was put out. We must continue to support them throughout the year to ease their pain as much as possible.”"Today, we will also remember the IDF's missing soldiers and the fallen soldiers whose place of burial is unknown, and we will pray that our children return to their own land."Over 1.5 million people are expected to visit military cemeteries spread across the country on Memorial Day.
