While we are rightfully focusing attention on other threats, such as a resurgent Russia and a newly assertive China, the threat of terrorism has not gone away. It is difficult to see how ISIS Islamic State of Iraq and Syria] is totally eliminated from Syria, and Al Qaeda, with its various branches, has not disappeared either. And while terrorists have physically spread out to more locations, some of them have become quite adept at operating online as well, instigating terrorist incidents in the West. US Central Command (USCENTCOM) is the unified command responsible for US security interests in 27 nations that stretch from the Horn of Africa through the Arabian Gulf region, into Central Asia.] Over the past 12 months, we have dealt with a number of significant challenges in Iraq and Syria, Afghanistan, Pakistan, Yemen, Egypt and the Sinai, the Bab-el-Mandeb Strait, and elsewhere throughout our area of responsibility. We are making progress in many areas, but much, much work remains. We are also dealing with a range of malign activities perpetrated by Iran and its proxies operating in the region. It is my view that Iran poses the greatest long-term threat to stability in this part of the world. Generally speaking, the Central Region remains a highly complex area, widely characterized by pervasive instability and conflict. The fragile security environments, which reflect a variety of contributing factors including heightened ethno-sectarian tensions, economic uncertainty, weak or corrupt governance, civil wars, and humanitarian crisis, are exploited by violent extremist organizations and terrorist groups, such as Al Qaeda and ISIS. At the same time, the Central Region is increasingly crowded with external nation-states, such as Russia and China, who are pursuing their own interests in attempting to shift alliances within the region.
