I'd be grateful for any advice on sentence 15 in the Practice and Review section of chapter 21.
The sentence reads;
Many nations which lack true peace are being destroyed by wars.
Benissimus' Key has,
Multae patriae bellis delentur quae vera pace egent.
Multae nationes, quibus pace vera caret, bellis delentur.
Is there any reason not to use 'carere' here? Is there a nuance I have missed somewhere? Also, what of my use of the relative pronoun? I trust (perhaps foolishly) that I'm ok with 'nationes' as legitimate variation.
Many thanks to any who can advise.
