Since 1979, the United States has led international efforts to use sanctions to influence Iran’s policies, including Iran’s uranium enrichment program. When nuclear talks between Iran and Western governments were stalled and seen as a failure, they were cited as a reason to enforce stronger economic sanctions on Iran. The UN security council found that Iran’s nuclear activities raised questions with the competency of the security council. The reasons for these bans is to censure Iran and prohibit its further nuclear activities.
