So I think the agreement of the destination country is necessary.
PreCheck or not, Australia, Canada and the countries in Europe are fine with being the destination country of flights from the US.
It's re-screening and data sharing practices that may be exposed.
Keep in mind that even before this latest adjustment to PreCheck, re-screening at EU airports for US-originating flights is the most common way of handling US-originating passengers transiting an EU airport. And also keep in mind that even before this latest adjustment to PreCheck, re-screening at EU airports for US-originating flights has not always (even recently) been required for handling US-originating passengers transiting some EU airports.
