The US is a net exporter of coal and since 2007, when gas really started to grow, coal imports have fallen and exports have somewhat increased. The good part is mining it in the US is just too expensive, so mines do close down, but it is not a clear win. https://www.eia.gov/energyexplained/coal/imports-and-exports.php https://ourworldindata.org/grapher/electricity-prod-source-stacked?country=~USA

As for the EU, there is a working emissions trading system, which limits emissions, so there is active cutting of fossil fuels and coal is the easiest to replace.
