Until the 1960s when libertarianism/leftism broke out, abortion wasn’t the answer.
But you know what they say about the genie being out of the bottle, ansel.
While I do not believe that abortion is the answer, forcing women to bear the children of rape also isn’t the answer.
Convincing them to do the right thing is the answer, and no, it isn’t likely that 100% of them will be convincible.
