the strict Jewish belief is that abortions are only allowed when the fetus is a rodef..meaning that it is endagering the mother's life.
My opinion, which counts for nothing, is that a rape victim should be allowed to be given that option of abortion or going through the full pregnancy term and deciding to give that child up for adoption or keeping it as her own child. I feel that today, most women are not perfect enough to lead a normal life if they were forced to give birth to a child as a result of rape. I just think forcing her to do so would be terribly wrong and doesn't serve the greater good. By the way, this isn't the strict Jewish perspective. The rabbis in their infinite wisdom agreed that abortions would be inappropriate even if a woman were raped--but if I'm wrong on this detail let me know.
As far as the US is concerned, I feel it is wrong to get politicians involved in allowing or disallowing a certain medical treatment. In a nation like the US which is not based on a specific theology three people shoudl be involved when a woman is deciding on whether she shoudl keep a fetus: Herself, her physician, and a spiritual leader of her choosing. All three need to choose life over death and be thoughtful on how to save the fetus's life. Obviously, in my opinion, the mother's life is more important to the fetus when it comes down to life and death.
