Maybe in the pre-Brexit or pre-Trump era but today... . I turned down a London offer because of the uncertainty Brexit brings and I'm certainly not alone.
It's not that Great Brittain or the US is that political stable with al that happende the last couple or months.
The conservative parties CDU/CSU are totally sane compared to large parts of the UK tories or the republicans in the US.
> AFD in Germany in the 15-20% range
According Wikipedia, no poll ever has given AFD more than a 15%, with the vast majority giving it around a 12.5% (https://en.wikipedia.org/wiki/Opinion_polling_for_the_German...). Even if AfD would get to 20% (which it's very far away from their predicted results) it's very unlikely they would get to the government.
> Le Pen might win in France
She might, but right now is very unlikely, much more than a Trump victory or Brexit. The problem is that she is losing in the polls by... a lot. For the French presidential election, all polls predict Fillon v. Le Pen. The only two polls conducted since Fillon was chosen candidate give him +34 and +42 (https://en.wikipedia.org/wiki/Opinion_polling_for_the_French...). 42 points was the distance between President-elect Trump and Johnson, the Libertarian candidate, in the last election.
I'm not saying it's impossible. Just very unlikely. The errors in the polling for the US Presidential Election and the Brexit referendum were much smaller.
Still, I don't think that Le Pen would be that bad, especially considering the failures of the two last présidents.
