US military power already far exceeds that of every other country on Earth.

That isn't entirely true. Looking at soldier numbers in general, NATO without the U.S. has ~ 1.2 Million active, the U.S. as a whole over all branches has roughly 1.4 Million - that's however including National Guard. Without that, it's 1.1 Million. Most NATO countries however do reserves different, Germany alone has 930k in Reserves (meaning, they either had military training or are receiving it on a rotational basis), the U.S. has ~ 300k. All of that combined gives Europe roughly 2.5 Million Soldiers that can be put in to service very fast. Since organizational structures are very similar on all accounts, if need be, that would happen fast. Remember, the EU also has very similar guarantees as NATO, meaning if one is attacked, the others vowed to help. If Europe actually tried with their military spending, we'd be able to outspend the U.S. by a lot - easily. Keep in mind...we're (=Europe) supplying Ukraine with more than the U.S. does, and most of our arms industry is still not even trying. Airbus, Rheinmetall, BAE, KMW, Navantia, Safran, ThyssenKrupp...they are all "trotting along" right now. Except Nuclear Threats, the U.S. hasn't got much to "best" others, IF Europe actually kicks in to gear (granted, that all needs the European Union not to crumble as well...) even technology wise the U.S. isn't that "overwhelming". Look up U33 and U32 - they both sank entire U.S. Carrier Groups in many simulations regularly - they still do. Hell, they even put two Los-Angeles class U-Boats to shame, they sunk them too. Most of the European U-Boats are pretty similar on that aspect as well, the Italians actually have the same and the French Triomphant-class isn't that bad either.

Germany's "collapse" of a Coalition is not necessarily something unprecedent. It has happened a few times and is also a sign for a very healthy democracy. In Germany, most of the governing power comes from ministries and state secretaries - those do not change with the collapse of a coalition. Our system is more robust than that of the U.S. against those kinds of issues (it isn't when the truth just get's thrown out of the window) - however, i also believe that the U.S. System is more robust than most of you give it credit.

And i agree, it's unfair, but as an educated immigrant, actually wanting to work and putting the effort in to learn the language and be considerate of the culture - you'll be fine, even with more right leaning governments throughout Europe.
