I think he is referring to the notion that Germany still owes Greece war reparations from WWII, which Greece put at 297 billion Euros [0] This is a hairy topic, with Germany insisting that these matters were closed in the Two-plus-Four Treaty, and Greece wanting to be repaid for their post WWII magnanimity, in addition to this being viewed as the Greek government trying to weasel themselves out of systemic issues and necessary reform using dubious legal claims. Germans, and younger Germans in particular may also view this as a "sins of our forefathers" issue, which also strikes a nerve, especially since the claim seems frivolous to many. If Greece were devastated by a natural disaster and demanded aid citing their waving of reparations more than 70 years ago, this would be viewed in a different light, but the general perception in Germany is that they brought this issue upon themselves, even though the situation is likely considerably more complex than that. Very very controversial, that's as much as I'll say. [0]https://en.wikipedia.org/wiki/German_reparations_for_World_War_II#Greece https://en.wikipedia.org/wiki/German_reparations_for_World_W...
