The money isn't really for the researchers personally, but for doing the research. They are merely offered a job at a time where their jobs are on the line in the USA. And not even that, they still have to apply and compete with top researchers from other parts of the world. Really hard to call that a bribe, even in a morally neutral way. At most you could say the Netherlands - and other European countries - are taking advantages of the situation where the USA is abandoning their top researchers.

But for years it has been the other way around. Top talent from the Netherlands has been moving to the US in order to get funding (and a bigger salary).

Sometimes. But bribery is also a crime, so using that word invites comment.

No we don’t.

> In the US we sometimes use the term “bribe” in morally neutral or even positive situations.

I live here in the US. I've NEVER heard the term bribe in a neutral or even positive way. It might be used in a mocking way, as if to mock the idea of bribes, but never seriously.

So, unless you are confusing that mocking nature as morally neutral or even positive, this is incorrect.
