“Wipe out”??
How?
Nuke them from Orbit?
EMT burst?
Oh, undercut pricing from US manufacturers who have a very, very limited US market, EEOC, OSHA, EPA, LGBTQRSTUV regulations, etc.
You mean like how Kawasaki, Nihon Sharyo, Bombardier, Alstom, Siemens and so many others “undercut” the nigh-nonexistent US railcar industry?
