Only Germany has a stronger stance on Israel, probably due to the large presence of Jews in the country.

You are misinformed. There hasn't been a large Jewish population in Germany since the Holocaust, and attributing Germany's support for Israel to an imagined one sounds, frankly, a bit antisemitic.

There are many EU countries with more Jews per capita than Germany. Less than 0.2% of Germany's population is Jewish, and less than 1% of Jews in the world live in Germany. 60% of Jews in Germany live in a single city (Berlin). Over 80% speak Russian, having immigrated there from former soviet states.

German politicians often say that, due to the Holocaust, support for Israel's security is part of Germany's "reason of state"; they tend to avoid discussing the Zionist view that Jews choosing to live in Germany today should also really move to Israel.
