A primary concern for many are train derailments across the U.S., some of which have resulted in ecological damage to surrounding areas, killing animals and contaminating the water supply. Such events are garnering closer national scrutiny.

The sharp focus placed on these incidents by media and online personalities has sparked concern that the destruction may be part of an asymmetric warfare campaign undertaken by one or more U.S. adversaries. Often named as a suspect is Russia, whose officials have vowed "consequences" after an explosive report was published by award-winning investigative journalist Seymour "Sy" Hersh, alleging that U.S. President Joe Biden ordered the destruction of Russia's Nord Stream 2 natural gas pipeline to Europe.
