Merz hails Germany's friendship with Israel on first visit

I frankly don't see how this has to do anything with anything. Merz has also openly criticised Israel and, at least briefly, halted arms exports to them. It's also news to me that being pro-Israel is a (far-)right thing in Germany.

For obvious reasons, Israel and Jews in general are a very touchy topic in Germany and German politics. Until the recent developments in Gaza, it was really hard to find any politician at all that would speak critical of Israel. That is probably because Israel and their institutions tend to respond very harshly to any criticism, and whatever you would said was guaranteed to backfire.

This has somewhat changed since it became hard to deny they are doing some pretty fucked up stuff over there. Blocking arms sales to Israel, even ever so briefly, could be described as a monumental policy shift from the formerly near-unconditional support that Israel was used to.
