>Isn't that a similar process to the US? Basically the currently ruling party gets to pick the supreme court judges.

The US Senate must approve all federal judges (among many federal posts, including the cabinet). If the president's party does not have a majority in the Senate, that means the president must nominate someone that at least some Senators from another party will vote for.

In Canada, UK, etc., whoever the PM says will be a judge becomes a judge; Parliament has absolutely no control over the process.

>Something like the supreme court deciding to overturn abortion legalisation is really unthinkable.

You seem to think—likely based on Reddit and Dutch reporters that just copy whatever the New York Times and Washington Post say—that abortion is "illegal in the US". The Dobbs decision in 2022 reversed the Supreme Court's own 1973 decision in Roe that abruptly voided all state laws banning abortion of any kind. In Dobbs, the court ruled that it had exceeded its remit, and returned the ability to legislate on abortion to the individual states.
