Question

explain in very a long way...
Stay in pact to entail regret or quit to ensure the nation`s disarmament?

Answer 1

Pact basically means agreement between two parties.

Regret means feel sad.

entail means involving something.

disarmament means peace basically.

So here the statement means that you need to maintain less wars to ensure that peace is maintained.
