The OPCW’s funding crisis is a threat to global security
With the United States withholding its financial contribution to the OPCW, the organisation faces a funding crisis that threatens its vital work. Former Director-General Ahmet Üzümcü argues that the OPCW has repeatedly demonstrated its competence and ability to adapt to changing circumstances, and urges Washington and other states parties in arrears to fulfil their financial obligations.
