Since Mahsa Amini’s death on September 16, protests in Iran have escalated, bringing increased attention to the Iranian government and the state of democracy in Iran. Meanwhile, Iran has continued to conduct a process called uranium enrichment, which involves the enrichment of uranium to higher levels of purity. This process is necessary for the development of nuclear energy and nuclear weapons. Western leaders and leaders in the Middle East have expressed widespread concern that this process represents a move by Iran toward nuclear armament. However, Iran has denied claims that the process is an act of nuclear proliferation, stating that the uranium enrichment process is being conducted for the sole purpose of the development of nuclear energy. Recent progress on this process shows Iran enriching uranium up to 60%, a significant rise on previous enrichment of up to 20% in 2015, but what does this mean for global security, and why are Western leaders and their allies worried by this development?
