"Much of anything" is a malevolent exaggeration. Germany is basically changing its entire stance on military spending, sending tons of weapons and other supplies to Ukraine, taking in hundreds of thousands of refugees and risking its economy by enacting strong sanctions and getting off imports from Russia eventually. For some people that is "not much of anything", but I suspect there is an agenda...
A refugee crisis isn't all that bad by the way. Politically it's a problem but economically a 2016 scale refugee crisis every year would be quite good for Germany. Germany needs huge amounts of people, especially people working in trades, to do the work necessary to switch heat pumps, install solar, build more housing etc. They have to come from somewhere and demographics means they have to come from a massive increase in immigration.
It's also economically unsound and technologically misguided, since nuclear power cannot replace the role gas has in the European grid.
