President Donald Trump is threatening to launch air strikes on Iran for activities that are approved under the terms of Iran's treaty obligations. This is not a matter on which there should be any debate. The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) explicitly grants all parties, including Iran, the "inalienable right" to develop, research, produce, and use nuclear energy for peaceful purposes. This "inalienable right" includes the enriching of uranium.

Trump either doesn't understand what a "treaty" is or thinks its terms should not apply to Iran. For the sake of clarity, a treaty is a formal, legally binding agreement between sovereign states that is governed by international law. It establishes mutual obligations, rights, or rules on matters such as trade, security, nuclear non-proliferation, or environmental protection. A treaty is not optional and cannot be repealed by executive fiat. States that ratify treaties are legally obligated to comply with their terms in good faith. Political leaders, as representatives of the state, are expected to uphold these obligations.
