You mean the self-reported ancestry poll which people larp about, when in reality Americans have a history of deception regarding reporting their own ancestry, and the average American has a disdain for the Anglos thus identify themselves as German? I don't buy it.
As for being "down under", you're part of the same Anglosphere problem, and sorry to say, but you will be isolated from Europe. It's very noticeable that Europe is drifting closer towards both Russia and China, this artificial war is going to slow that down a little, but it is still inevitable, whilst benefiting Europe in the sense of the diversification of the energy sector.
Germans and Anglos aren't brothers, you're clearly uneducated regarding history. The Anglos, being of partial Germanic descent, adopted Germanic culture after the replacement of their elite by the Angles, Jutes, Frisians, and Saxons from the continent. The same group of people have been historically opposed to German interests, which is why they fought against their own interests, which is why their children get gangraped by grooming gangs, just to fuck over Germany with the other two great empires. What kind of brother, perverts history to make it seem like you're the bad guy, enslaves you for 10 years, gangrapes and murders millions of your people, starves to death millions of your people after the war, use your people as human experiments after the war, steal your science to claim it was theirs? The whole "no more brother wars" idea is a ridiculous Anglo way of begging for unity when the Anglosphere is falling apart, after it contributed to the ruination of Europe. I suggest you look into 19th century German history, which is the point in history where the concept of "Germandom" was created, the Anglosphere was not a part of it for a reason.
The current Germany is held back by that forced integration with the Anglosphere, but that has been noticed and they will gradually move away from it. The Anglo containment strategy against China, whom your people also created through greed in searching for cheap labour, is far too late and has already failed. Most of Europe are still trading with "le ebil Russians" even though they're supposedly in an alliance with you. NATO is a paper alliance, many of whom (Turkey and France in particular) compete for military dominance in Africa, nobody is willing to die to protect the US or the UK's interests.
