Merge tags "abroad" and "offshore" into tag "international" and establish tag synonyms?

Question

Do we really need the abroad and offshore tags? We already have the international tag which is used far more often than either of the aforementioned.

Answer 1

Agreed. In principle offshore has slightly more specialised connotations than international but I don't think it's worth it to try to draw the distinction in practice.
