7. FREQUENT TERRORIST INCIDENTS ROCKING WESTERN SOCIETIES

On Oct. 1, a mass shooting killed 59 people and injured 527 at an open-air concert in the western U.S. city of Las Vegas, making it the deadliest massacre in modern American history.

The attack reflected a series of social ills in Western countries, such as the rampant gun control, the deeply ingrained violence culture, and the intensification of class division.

This year has witnessed over 300 fatal shootings in the United States, as well as frequent outbreaks of terror in Europe such as Manchester concert bombing, Champs-Elysees shooting in Paris, and van attacks in Barcelona.

Reports of the Australian Economics and Peace Institute showed that the number of violent deaths in the United States as well as the developed countries in Europe in 2017 is expected to hit a record high in the past 16 years.
