About Category:Failed terrorist attempts and related categories The scope of this category includes pages whose subjects relate to terrorism, a contentious label. Value-laden labels—such as calling an organization and/or individual a terrorist—may express contentious opinion and are best avoided unless widely used by reliable sources to describe the subject, in which case use in-text attribution. Avoid myth in its informal sense, and establish the scholarly context for any formal use of the term.

These are cases of attempted major attacks which either were foiled, or which failed to have their intended destructive results.
