World Against Violence and Extremism

WAVE is an acronym for "World against Violence and Extremism" (In Persian: جهان علیه خشونت و افراطی گری) suggested by Iranian President Hassan Rouhani. The United Nations voted approve President Rouhani's WAVE proposal at a general assembly in December, 2013 which resulted in a call for all nations across the globe to denounce violence and extremism.

In December, 2014, Tehran held a 2-day WAVE conference with representatives from more than 40 countries. This conference was referred to as, "the beginning of a new international coalition against extremism."
