Its happening today , now remember I don't give a shit about any coal production other then Manchins coal production. , His mines are in the US, something you don't seem to realize. , don't care at all about production anyplace else in the world . Down half in west Virginia from 2008 to 2016 , that's just 8 years ,Down half in this country from 2010 to 2020 that's in 10 years. Take away the American market for coal and Manchin is down the shitter. So I say go for it and it can be done . the threat will be under the table for Manchun and denied denied denied to anyone else.
