reunification

[AirbusA321]

Please check if both versions are possible and which one would be better.

Margaret Thatcher hated Germany so much that she even tried to sabotage the German reunification - fortunately she failed all along the line.
Margaret Thatcher hated Germany so much that she even tried to prevent Germany from reunifying - luckily she failed across the board.

Replace the dashes with periods ("full stops" in British English), capitalize the following letters, and you'll have four correct sentences.

Neither "all along the line" nor "across the board" works well for me. A single-word adverb like entirely or completely would be fine.

I'd remove the definite article before "German reunification" in the first. I agree with GS about "all along the line/across the board" not working.
