From the Document: "With increasing numbers of incidents, the use of chemical weapons (CW) has become a growing international concern two decades after the international community decided to ban them under the 1997 Chemical Weapons Convention (CWC). The United States has said [hyperlink] that Russia may be 'planning to use biological or chemical agents against the Ukrainian people ... for assassinations, as part of a staged or false flag incident or to support tactical military operations.' [...] The Organization for the Prohibition of Chemical Weapons (OPCW), originally established to oversee the destruction of chemical weapons stocks under the CWC and promote the safe and peaceful use of chemicals, now has additional challenges and responsibilities. [...] Congress may wish to consider how best to respond to the use of chemical weapons, including how future use could be deterred, and whether U.S. forces are adequately protected. Congress may consider whether the OPCW has adequate resources for investigations, and examine efforts to curb proliferation of CW-related material and technology, such as interdictions, international sanctions, and export-control assistance programs."
