@derPUPE Doesn’t get enough attention. This stuff is scary. Then again, it makes me respect the Dutch even more for their foresight and the investments that resulted. I wonder whether any of that would still be possible today in an economic climate with a 3-month window and a political climate focused on scoring today.
@hvdsomp @derPUPE It's not (or not only) foresight, it's hindsight with respect to the 1953 flood.
