LAWRENCE WITTNER – Based on both international law and precedent, the UN Security Council has the authority to impose a settlement of the disastrous Ukraine War. What kinds of international action this would require would need to be determined by the world organization, just as the final terms of a peace agreement would ultimately need to be accepted by the contending parties. But, given the overwhelming support in the UN General Assembly for the withdrawal of Russian military forces from Ukraine and for a lasting peace agreement, such a peace settlement is likely to be a just one.
