Kim Jong Un already pulled that trigger.

The Trump administration’s primary North Korea strategy would do little to curb the country’s nuclear program and could trigger a famine, according to experts.
After spearheading several rounds of sanctions, the White House is now urging China to turn off oil supplies to Kim Jong Un’s regime and the 25 million people he rules.
Lt. Gen. H.R. McMaster, President Donald Trump’s national security adviser, summed up Washington’s thinking Sunday: “You cannot shoot a missile without fuel.”
Many analysts say such a move would have minimal impact on North Korea’s nuclear and missile programs and would instead hit the country’s agricultural sector, potentially leading to mass starvation.
“If it could be done, a full oil cutoff would certainly dramatically reduce the amount of domestically grown food available to the civilian population,” according to David von Hippel, a senior associate at the Nautilus Institute for Security and Sustainability, a California-based think tank.
Von Hippel warned the results of an oil embargo — which he conceded would be almost impossible to enforce — could have a catastrophic impact on a humanitarian level.
“Unless China or the rest of the world exported or gifted food to the DPRK to compensate, this would likely lead to famine,” he added, referring to the North by its official name, the Democratic People’s Republic of Korea.
