Correct on a per capita bases Portugal has been growing much much faster then Germany. The simple truth it that Germany is not benefiting from austerity either. What should happen is that the German government massively increases spending. This would turn Germany from a net exporter, to a net importer. That allows the PIIGS to export products to Germany paying down the debt, but it also stimulates the economy. Germany profits from the increased spending as well.

The simple truth is that German life expectancy is declining since a couple of years(being below Spain, Italy and Portugal btw). Median wealth of Italy, Spain and Portugal is higher then that of Germany, which is only slightly higher then that of Greece. Real wages in Germany have gone up by 3.8% over the last decade(not annually but the entire decade).

The only ones who really profit from this austerity are the super rich. Other then that it is as bad a policy for Germany as it is for Italy, Portugal, Spain or Greece.

Spain has grown faster then Germany for most of the last decade(besides 2020). Out of PIIGS Portugal and Ireland also have done pretty well. Greece got hit hard and Italys economy has problems since the 90s(aka not a EU/Euro problem).

Also Norway is not an EU member.

If only Germany would not be willing to recognice Palestine, then this might happen, but that is not the case. France and Italy the two next most powerfull countries do not recognice Palestine either.

Germany is usually fairly happy with the current state of the EU. The things Germany wants to change are usually also supported by Spain and that means blackmail is harder. The only exaption to that is finance. However Spain is not going to let billions go to waste to have Palestine recogniced. That is just more of a symbol, rather then massivly important.

Also Germany leaving the EU would cause some massive problems in other EU countries as well. They would hardly be cheering for it.

Foreign policy needs consensus. So the EU can not force Germany to do anything in terms of foreign policy.

Unlikely. Germany most likely is not going to recognice Palestine for a long time.
