"5. North Korean Overseas Workers (OP8): Requires countries to expel all North Korean laborers earning income abroad immediately but no later than 24 months later (end of 2019)."
"Strengthens the ban on providing work authorizations for DPRK nationals by requiring Member States to repatriate all DRPK nationals earning income and all DPRK government safety oversight attachés monitoring DPRK workers abroad within their jurisdiction within 24 months from 22 December 2017."
Meanwhile the DPRK has no official restriction on the people's free movement.
Blaming others for one's own actions has got to be one of the greatest propaganda achievements in human history.
Assuming good faith, the liberal notion that the UNSC in this case is acting out of a neutral concern about nuclear weapons is completely contradicted by the reality that similar restrictions aren't placed on Israel.
Israel has an illegal arsenal of nuclear arms and a stated policy of massive retaliation. Its nuclear arms are also in violation of the NPT which is cited in your UN source repeatedly. It is also an American proxy state, established through terrorism and expanded through racial violence and settler colonialism. Its nuclear arsenal exists to safeguard the continued expansion of this racial violence, genocide and apartheid.
The US has historically used intimidation and coercion to manipulate the UNSC against its geopolitical enemies, and this is no exception. The US waged a genocidal war against the DPRK during the 1950s, which is still technically ongoing. The war effort not only involved massive bombings of civilian infrastructure, but also assistance to the RoK government, staffed by myriad Japanese collaborators, in murdering anyone suspected of sympathy with the DPRK.
Pleass ask yourself why the DPRK is subject to a legally binding UNSC resolution, while Israel gets a gentle suggestion from the UNGA to pwetty pwease disarm for the exact same crime, though with drastically different motives.
