The 2015 European Immigration Crisis brought an unprecedented number of immigrants to parts of Western Europe as millions of people fled war-torn and politically unstable countries. Similar to the increase in immigrants, Western European countries have also been combatting the rise of terror attacks throughout Europe. The increase in immigration coupled with an increase in terror attacks has caused anti-refugee sentiments among some Europeans and demands for stricter immigration policies. This paper examines how terrorism has impacted refugee and immigrant populations throughout Western Europe with a focus on Germany, France, and Belgium following the 2015 European Immigration Crisis. In order to determine the effects, the analysis focuses on recent terror attacks in the three nations. The claim that refugees are responsible for the increase in terror attacks is examined along with the impact of foreign terrorist fighters in each nation. Following this, the responses from right-wing groups are discussed. This includes the rise of right-wing political leaders, the organization of right-wing movements, and right-wing terror attacks. The resulting policy implications regarding both terrorism policies and immigration policies are also discussed. From these three areas of impact, the overall effects of the European Immigration Crisis are better understood.
