Globalization has both decreased the costs of travel and increased the scale of operations for terrorist groups. Individuals can now easily and relatively affordably (at least individuals in developed countries) travel to various areas of the world for short holidays; however, the same ease of travel – along with the growth of open societies – has allowed extremist groups to target travelers in either less secure countries or in more open ones. This has created, for some, caution when traveling abroad as individuals are reticent to leave the known security infrastructure of their home country for the unknown infrastructure in another country. Nevertheless, people do and will continue to travel abroad extensively and, therefore, individuals must be cognizant of the relative risk present in their destinations. Some regions have no known or publicly disclosed terror threat; others are known to receive threats constantly.
