It shouldn’t come as a surprise that the country who effectively eradicated Jewish life in Germany and large parts of Europe is backing Israel. According to Wikipedia there are only 120 synagogues in Germany, compared to ~45 000 churches and ~2 700 mosques today. Before Nazi Germany there were around ~2 800 synagogues.
The German state and every German citizen has the historic obligation to protect Jewish life.
The easiest way to project this outward to the public is to support the only state founded upon Jewish tradition, in comparison to the plethora of Christian or Islamic tradition ones.
That the Israeli government is right wing is imo obvious and Israeli citizens are apparently fed up with it as well.
I hope that the killings end and that there is a way for peace and cooperation in the region. Every person using an ideology/religion to divide rather than connect shouldn’t be considered a good human in any society.
No shit sherlock
