Ah, but English says "The Netherlands", "The Philippines" (Hello!), "The Gambia", and formerly, "The Sudan". Certain countries take the definite article in English; some still do as English grammar requires, others have since discarded it. And I should also note that it's hardly 'nobody'; depending on the language, and the usage case within that language, an article may be called for. In the two Philippine languages I know, a declarative sentence requires the article - "France is a country in Europe" must be "Ang France ay isang bansa sa Europa", the article in this case being 'ang'.

Language issues aside, we welcome further posts on the matter of Ukraine versus its article, so anyone with the insight should feel free to post! For the meantime, OP, we do have some previous posts on this matter:

• u/The_Manchurian looks at why some countries take the definite article and why some don't;
• and a now-deleted user has a thorough treatment on Ukraine specifically, with a special language note within; though treat that with care, it's seven years old as of time of posting.
