Most terrorists were believed to pursue limited political objectives and feared retribution. The most likely source of those dangers was a violent strain of Islamism, an activist movement devoted to purifying the Muslim world and restoring the glories of the medieval caliphate. Psychology alone would not have been enough to trigger the policies that emerged as it required a larger intellectual and structural context. This is where Middle Eastern politics and American hegemony come into the picture. They instilled fear and a desire for revenge, loosened the domestic constraints on the deployment of American power, and led not simply to increased counterterrorist efforts but to a grand campaign to achieve total security by fundamentally transforming a broad of the world. So, a lot of violent attacks make people live in fear, anger and depression.

The article mentioning on the War on terror and the central challenge to United State foreign policy. There are three kind of US foreign policy that author mentioned namely consolidate, protect, and extend the liberal international order which is benefiting to US and the others countries in world. The first challenge that facing by US is threat of terrorism attack. For example, the bigger attack where it happened on 9/11/2001 in New York that killed thousands of people. This challenge has been become a concern to US and the writer have mentioned ‘It was inevitable that the attacks would make the fight against al Qaeda and other jihadists the top priority of American policy’.  Besides, to counter the terrorism, the Bush administration strengthened global counter terrorist operations and intelligence gathering, and paid more attention to homeland security. 

Second is threat by the great power conflict that also driven by globalization. They began to take their safety and prosperity for granted. 

The challenge we face here is to understand individual and organisational responses to low probability, high impact events, and to develop strategies to overcome the weaknesses of these responses and manage these risks. The 9/11 attack resulted in the change of the US Foreign Policy. We could see as the growth of the globalization had make the policymaker and leader to rethink on how to ensure everything is under control what constitutes an effective approach to deal with the threat of terrorism. In the aftermath of 9/11 attack, we knew that The United State was revising its national security structure.  There are many reasons why Bush took such actions during his administration. It simply because the attack by the radical group, Al-Qaeda was during the rise of American country. In addition, Al-Qaeda whom aim to re-shape the Muslim world have a quite strong political and economic in the Middle East. Literally, the attack was reminded the American with the Pearl Harbor attack the geopolitical effect of the 1950 communist invasion of South Korea. The challenge we face here is to understand individual and organisational responses to low probability, high impact events, and to develop strategies to overcome the weaknesses of these responses and manage these risks. Barrack Obama got to deal with the catastrophic economic prior to the Bush action to combat the terrorist. 

psychological stability as well. the terrorism group are al-qaeda. even thought this terrorism group are more powerful now, but they are not a winner because their objective and goal are not clear and transparent. so, US has introduce their foreign policy as to address and to control the movement of terrorist group such as  consolidate, protect, and extend the liberal international order. This order at last has

been the framework within which local economic, social, and political development has

proceeded, to the lasting benefit of both the United States and the world at large. the evolution of movement of terrorist group are flow by the globalization. their propaganda are seems holy enough, like violent strain of Islamism, an activist movement devoted to purifying the Muslim world, overthrowing “apostate” regimes there, and restoring the glories of the medieval caliphate. but actually there are agenda behind it.  for instance, On

September 11, 2001, these concerns merged when a score of radical Islamists from a group

called al Qaeda hijacked four civilian jets and flew them into targets in New York and Washington, killing thousands. so that the reasons why the George W

. Bush administration overdid it after 9/11. US as a big and superpower state are obligated to overcome and cut the movement of this terrorist group from keep arise and make world worst in future
