According to terrorist threat scenarios, what is the most feasible way terrorists can acquire chemical and biological agents?

The most feasible way for terrorists to acquire chemical and biological agents lies in constructing weapons that utilize them. This option emphasizes the practical application of existing knowledge and technology, which means that while it is theoretically possible for individuals to manufacture such agents, the complexities involved in doing so safely and effectively make it a less viable option.

In practice, many terrorist organizations may have limited access to the advanced scientific knowledge and sophisticated facilities required to produce their own agents from scratch. Instead, the focus often shifts towards adapting existing materials or exploiting vulnerabilities in supply chains to obtain or repurpose agents for their needs. This approach allows for a more streamlined method of weaponization, as it leverages knowledge of how to employ these agents within available capabilities.

Moreover, the construction of weapons using chemical or biological agents reflects a tactical use of resources. It encapsulates a broader understanding of not just obtaining the agents but also effectively delivering them, which is crucial for commissioning an attack. This makes constructing weapons with utilized agents a strategically feasible choice for terrorists looking to maximize impact.

Other options suggest scenarios that either minimize the complexity of acquisition, misrepresent the effort involved, or imply an unrealistic ease of access to these dangerous substances.
