Germanys and most of Europes conservative view would be considered "left" in the US
Its not that easy. The political spectrum just isn't really comparable between the US and the EU.
The US is for example discussing stuff like universal healthcare, free college education, paid maternity leave etc. Being for that stuff makes you left wing in the US.
All these things are a given in Europe. Not even the most extremist right winger would oppose them.
That kind of libertarian, "small government", fiscally conservative right just doesn't exist in Europe.
Its socially conservative parties and the next step to the right is nationalist ones. And when its comes to the nationalists the spectrum goes full circle because they usually are big fans of socialist policies.
So if we compare these politicians and judge them by American standards we have too look at groups of issues individually.
On social issues Merkel is mildly conservative rather centrist, basically like Obama or Hillary Clinton 10 years ago.
On social systems Merkel is clearly left wing, like Bernie Sanders but more coherent.
On foreign policy Merkel is definitely a globalist rather than a nationalist.
On environmental issues she is progressive.
Germany needs massive improvements
