As evidenced by the Brexit vote in England and the success (hopefully transient) of Donald Trump's Candidacy, nationalism is on the rise across the globe, especially in developed Western countries. This movement seems to have its roots in the inequalities of globalization and the fear of immigration (especially in light of recent terrorist attacks). Of course, racism and religious zealotry are at play as well.
Unfortunately, some politicians are taking advantage of the anger, fear and intolerance, placing emphasis on the risks of globalization and promising to protect legal citizens from the dangers of immigration, trade agreements and "cultural dilution." Older, less educated and more provincial individuals, many having lost their jobs to outsourcing and failing industries (e.g. coal mining, manufacturing, textiles), are most receptive to their message.
While some of these inequities and concerns are legitimate, globalization is here to stay and international cooperation is vital in our efforts to assist developing countries, to prevent war and to combat the threats of pollution, ecologic degradation and climate change. In the end, we must address the problems associated with globalization without resorting to nationalism; otherwise, we will destroy both our economy and our planet.
