As evidence mounts that chemical weapons were used last week in Syria, and the White House deliberates on U.S. responses, Here & Now turns to international security expert Jim Walsh to ask:
- What is a chemical weapon and what kind of stockpile does Syria have?
- Which other nations possess them and who manufactures them?
- What are the technological hurdles both for manufacturing chemical weapons and for using them?
- How much trade is there across borders, in fully developed chemical weapons and in related materials and technology?
