Why are large-scale chemical attacks difficult to accomplish?

• A. They require advanced equipment
• B. Materials and chemicals are hard to acquire
• C. They are easily detected
• D. They are not lethal

Answer: (B)

Access to the right chemicals is tightly regulated and monitored. Many of the substances that could be used in a large-scale chemical attack are controlled or dual-use, with licensing, verification, and import/export restrictions. Suppliers screen buyers, verify legitimate purposes, and law enforcement keeps a close eye on suspicious orders. As the desired quantity grows, the chances of triggering regulatory checks, red flags, and inspections rise, making it much harder to obtain the necessary materials. Even with the know-how to disperse or deploy them, the logistical hurdles—finding legitimate sources, passing regulatory barriers, securing storage, and transporting hazardous materials safely—create substantial obstacles to scale. The other factors—whether equipment is required, how easily something is detected, or the lethality—do not address the fundamental bottleneck as directly as access to materials does. That procurement challenge is what makes large-scale attempts particularly difficult.
