Gun owners need this to be sure, but infanticide is not acceptable at all. Nations with the blood of innocent children on their hands will not go unpunished by God. IMHO.
Like I said before, there are other ways to end abortion. Haven't abortions been on the decline? That is because of education, abstinence, faith, etc.
As for God's punishment, I am not worried about it as I am not involved in it.
