BREAKING:🇰🇵 North Korea imposes the death penalty on anyone who promotes Zionism inside Korea and describes Israel as an illegitimate entity.

Zionism is the belief and movement that Jewish people have the right to their own national homeland in their ancient historic land (now Israel). 

It started in the late 1800s so Jews could live safely after long history of persecution elsewhere. Supporters see it as basic self-determination, like any other ethnic or religious group having a country. 

That's the core idea in simple terms.
