This article aims to explore the current measures related to the prevention of violent radicalization that leads to violence and terrorism, exploring the different dimensions of the phenomenon of radicalization and extremism, which cannot be applied to certain stigmatized communities but to a wider spectrum of different political violent ideologies. At this point the proper use of terminology in this field can help us to understand how to address this challenge as a whole. Countries such as the USA and different International Organizations have carried out a set of measures to prevent violent radicalization but not always in a successful or effective way, although many initiatives at a local level are showing promising results. There is still a lot of work to be done not only in the field of prevention, but also in the de-radicalization one, measures should be more efficient.
