Many of the anti-Western terrorist organizations are especially active in supply chain terrorism. An example where both a supply chain and anti-Western terrorist attack occurred was the Yemen bomb plot, in which the terrorists used the supply chain to facilitate the movement of a PETN explosive device destined for two synagogues in Chicago. Another infamous incident was the attempt to attack container ships on the Suez Canal.
Anti-Western terrorism is one of the prime indicators governments look at for C-TPAT, PIP, and AEO compliance. Governments use these indicators from a risk-targeting perspective in order to determine which specific forms of validations should be conducted: for example, which containers to inspect, or which terrorist organizations are active in which countries that are likely to target the supply chain.
