Menopause is the point in time when a woman's menstrual periods stop. Menopause happens because the ovaries stop producing the hormones estrogen and progesterone. Once you have gone through menopause, you can't get pregnant anymore.
Initially the UN Security Council imposed stringent economic sanctions on Iraq by adopting and enforcing United Nations Security Council Resolution 661. After the end of the 1991 Persian Gulf War, those sanctions were extended and elaborated on, including linkage to removal of weapons of mass destruction, by Resolution 687.
Since bilateral sanctions are enacted by groups of countries, they can be considered less risky because no one country is on the line for the sanction's result. Unilateral sanctions are more risky, but can be very effective if enacted by an economically powerful country. Another way of categorizing sanctions is by the types of trade they limit.
