Since I first visited Germany, I was struck with how familiar it was. The food in particular was basically a minor variation on what we think of as traditional American food: frankfurters, hamburgers, pork chops, fried chicken, and countless variations on frying or mashing potatoes.
The beer is outstanding, and served agreeably cold.
In the fifteen years since, this sense of cultural affinity has only grown, and looking at world events, I think German politics and political norms are also closer to the present United States than that of Great Britain. Put simply, our English heritage has been superseded by the massive waves of German immigrants.
To be sure, Germans arrived long before the Revolution, and it's interesting to note that the drillmaster of the Continental Army was not English, but German. Friedrich von Steuben was a seasoned Prussian Army officer whose career in Europe had gone into terminal decline. Upon the outbreak of the American Revolution, he offered his services to help train and discipline the young rebel army. As a result, the Continental Army became more disciplined, effective and the drill manual he wrote became the foundation of American arms.
This is why American troops march and salute using a German style rather than stomping with each order and using a palm-outward form of salute as the British Army and its many descendants do.
Another German military innovation was the long rifle, variously attributed to Pennsylvania or Kentucky but developed in the Rhineland. This hunting weapon proved to be highly effective at targeting British officers, and played a crucial part in their defeat at Saratoga. The emphasis on precision marksmanship as a foundational principle of American Army doctrine continues to this day.
Much of that tradition of marksmanship is sustained by hunting, and Americans have a very German attitude towards the sport. In the UK, hunting is only for the elite and their friends. I've chatted with British gamers for many years online and the notion of a suburbanite buying a rifle and going out on state land to harvest deer is simply inconceivable to them.
In Germany, however, it is considered part of one's basic rights and culture. Germany has embraced an American concept of game management, which uses hunting as way to keep animal populations in balance. Just as in the US, Germans are required to take a qualification course in order to obtain a license. German firearms regulations are of course far more restrictive than the US, but much less stringent than those found in the UK.
According to various international surveys, approximately 20% of Germans own firearms, a rate of ownership four times that of the UK. It's interesting that Austria, which is of course also German, has a 30% rate of firearms ownership.
What this means is that the "gun culture" of German-speaking countries is much stronger than English-derived ones. The US is very much an outlier among the Anglosphere. I will note that German legal protections for self defense are less sweeping than those offered in America, but they are vastly superior to those in England, which are practically non-existent.
Another interesting point of comparison can be found in the weapons industries in the various countries. Arms manufacturers in the UK are almost non-existent. Even the ones that are still in operation have outsourced production to Italy.
Germany of course has Walther, SIG-Sauer and Heckler & Koch. Tiny Austria boasts Glock and Steyr.
Firearms ownership brings to mind another German-American similarity: a written federal constitution. The British famously use an unwritten constitution. While the UK is "the mother of parliaments," the US took a different path, preferring a federal republic to a unitary state.
Like Germany, the US is an aggregate of states, and this similarity was noted in the Federalist Papers, albeit unfavorably because at that time, the Holy Roman Empire was generally fragmented and weak. The Federalists liked the autonomy of the various baronies, counties and duchies, which could levy their own taxes and even support their own armies, but the weakness of the Emperor invited constant conflict both within and without.
Intriguingly, the Founding Fathers borrowed a concept from Germany rather that creating a parliamentary system. The Holy Roman Emperors were not hereditary monarchs in the English sense. The position was actually an elective one, chosen by seven specially designated "princes" of the Empire. These were the Imperial Electors (hmmm, familiar term), and while certain families (like the Habsburgs) tended to 'inherit' the honor, it is worth noting that as late as 1748, the succession was disputed by divided Electors.
The US similarly has a special group of people who are outside the normal political sphere - the Electoral College. Their only duty is to choose the next president.
Heck we even drive on the same side of the road as the Germans.
I could go on, but I think the point has been made - American culture has quietly shifted to be more in alignment with that of Germany over England. This would be even more apparent if the World Wars hadn't caused Germans to aggressively drop their language and overt displays of ethnic loyalty. Oktoberfest is about the only explicitly German thing left. Even the foods have had their names worn down into "hot dogs" and "burgers."
But if you're paying attention, it's hard to miss.
