Hello. I'll be very grateful if you help me with a few questions.

1)Would you use the article in the context: "he became (the?)French president", "he became (the?) president of France"?
2)Which preposition is correct in the following context: "England settled its people in/on (?) the new territories"?
3)Do you think it's possible to use "win" in the political context, for example "the country had a historic win" (it's not about sport)?
4)Do you think the sentence is correct (I mean its second part)"Palestine achieved a diplomatic victory with its entry (entrance)to Unesco"?
Thank you very much for all your help and attention.

1. Yes, use 'the' In both instances.

2. Use 'in.'

3. I'd need to see the whole context.

4. I'd use 'by' but both prepositions would work.
For 4, 'entry into ...'
