What Europe should do RIGHT NOW: Make it extremely easy for US scientists to get long-term visa, create as many additional research jobs in key areas as possible, create new, generous science and research funds. People are losing their jobs over there NOW. Let‘s welcome them.
@chrisstoecker Unfortunately, this will not work. Not only does Europe only have a fraction of the research positions available that the US has (i.e. we can't even absorb la crème de la crème from the US), Europe has also only a fraction of the research budget available. I.e. even if we could hire all these scientists, we can't finance the research they want to be doing.

@chrisstoecker
The scientific culture in Europe is very different and there is a lot less money available. All that the Trump administration achieved is, that the conguested situation in Europe is getting even worse.

And, unless the conservative parties that have been on the rise for the past 2-3 decades, suddenly change their opinion of science i.e. don't think it's a waste of money and resources anymore, we will not become a science and research power house.
