In Western Europe, too, abortion is available on request only in some countries, and even there usually only during the first trimester, and it often comes with various restrictions (such as limited grounds on which abortion is permitted, need for approval by a physician or a medical committee, compulsory counseling, waiting periods, etc.) placed on it: <http://www.un.org/esa/population/publications/abortion/index.htm>.
Liberalization of abortion laws is also historically recent in Western Europe: "In West Europe, almost all decisive reforms were effectively carried out between 1970 and 1990" (Irene M. Tazi-Preve and Juliane Rolof, "Abortion in West and East Europe: Problems of Access and Services," 25-30 November 2002, <http://www.cicred.org/Eng/Seminars/Details/Seminars/Bangkok2002/32BangkokTazi&Rolof.pdf>).
That's not very different from the very religious USA, which legalized abortion in 1973, and some countries in Western Europe legalized abortion much later than in the USA. E.g., the Swiss didn't legalize abortion until 2002 (see <http://news.bbc.co.uk/1/hi/world/europe/2021121.stm>), even though the Swiss church attendance rate is in the same league as France, which legalized it in 1975: <http://www.religioustolerance.org/rel_rate.htm>. -- Yoshie
