The world already knows that Bashar al-Assad has used chemical weapons, indiscriminate bombing, arbitrary detentions, rape, and torture against his own citizens. What is far less well known, and equally intolerable, is the systematic denial of medical assistance, food supplies, and other humanitarian aid to huge portions of the population. This denial of the most basic human rights must end before the war’s death toll — now surpassing 100,000 — reaches even more catastrophic levels.

Reports of severe malnutrition across vast swaths of Syria suffering under regime blockades prompted the United Nations Security Council to issue a presidential statement calling for immediate access to humanitarian assistance. To bolster the U.N.’s position, every nation needs to demand action on the ground — right now. That includes governments that have allowed their Syrian allies to block or undermine vital relief efforts mandated by international humanitarian law.

Simply put, the world must act quickly and decisively to get life-saving assistance to the innocent civilians who are bearing the brunt of the civil war. To do anything less risks a “lost generation” of Syrian children traumatized, orphaned, and starved by this barbaric war.
