The reason Germany gets singled out is because it was a massive policy misstep and highlights the shortsightedness of the environmental movement. It seems that they have changed their tune about it nuclear - but their entrenched efforts (and concerns in the 80s) killed the last 40 years of nuclear power - arguably inflaming our current CO2 crises by opening the doors wide open for Oil and Gas to fill the void.

In Germany add in that they then needed to rely on Russia to provide natural gas to fill in the void - which drove up the costs of power and made their manufacturing base a little less competitive.... Best intentions don't always prove to be good policy making. That's the TL;DR why Germany gets singled out.

Unlike the states, Germany is densely populated and does not have vast uninhabited areas. Where do you suggest should they store their nuclear waste? Germany has been looking for an appropriate place for the last 50(!) years and does not expect to come to a conclusion any time soon:

In the mean time, they're keeping they're using the sites of their former nuclear power plants as temporary storage locations for the nuclear waste produced while the plants were still running.
