> Many reputable democracies[1], including Germany, Australia, Norway or Switzerland, have a reference to god in their constitution

None of these say that their states are Christian and Democratic, nor do they have government decisions finding that this means anything at all. In Israel, by contrast, their highest court has found that, for example, a right to return for Palestinians would be unconstitutional - as it would undermine the Jewish character of the state of Israel. A reference to some god in their constitution would be a completely different thing.

> That in turn isn't government directive, but a political opinion amongst several.

This is an extreme downplaying of what I said. Several of the people in charge of the Israeli government have explicitly and exclusively, religious motivations in their decision making - that is a very clear sign of a form of theocracy.
