This bill matters because it changes a temporary policy into a permanent one, ensuring long-term pressure on Iran. If this bill passes, the United States will continue to use economic tools to try and curb Iran's illicit weapons programs and its support for terrorism, without needing to renew the sanctions periodically.

If it doesn't pass, the existing sanctions would eventually expire, potentially reducing the economic pressure on Iran and altering the U.S. approach to foreign policy in the Middle East. This bill signals a long-term commitment to a specific strategy regarding Iran, which could impact regional stability and diplomatic relations.
