Earlier quoted context omitted.
English is spoken very widely in Ukraine in fact, and was just promoted to an official status (not as a primary language, but to a secondary official status nonetheless) in the past month.
So, maybe that is the difference to the German language? Here in the news you can hear "die Ukraine" (the Ukraine) all the time. And usually any "rules" in the rough vicinity of political correctness, anti-discrimination or simple politeness are meticulously adhered to in German news. Which I am personally fine with.
If anything the connotation is the opposite from English -- articles are generally more attached to certain countries for which Germany has historically had significant relations (for good reasons or bad). In modern times though, it's just another fussy part of the language that one is obliged to put up with and not give a second thought to. One simply has to say "im Frankreich", "in der Türkei", "im Iran" and so forth (but also not attach the article to most other countries), and that's all there is to it.
I wish I could point to an authoritative reference for this, but that's impossible nowadays that we have the zombie internet and everything online has been reduced to shitty apps, flashcards and "didya know?" pages.
