Yep, it happened: https://www.nytimes.com/2017/08/14/worl ... ctory.html
Long story short: In 2014 the couped-in "Government" picked a fight with Russia, and Russia promptly suspended orders from Ukraine that Russia was not bound to upkeep. (Yep, that gas pipeline is going bye-bye in 2019.) One of the suspended orders came from a plant producing engines for nuclear missiles. Without orders, the plant fell on hard times, and the nuclear scientists were unemployed. Instead of doing something intelligent, (like employing these guys,) the couped-in "Government" did what they do best: blame Russia.
Enter North Korea. They recruited some of these scientists and got a copy of the design. Starving in Ukraine or being treated like royalty in North Korea - not exactly a hard choice. And they don't even have to buy meth!
Those engines were linked to only a few former Soviet sites. Government investigators and experts have focused their inquiries on a missile factory in Dnipro...
Why would Poroshenko watch what the nuclear scientists do when he has much more important things, like toppling Zhukov statues, renaming random cities, and posing for Russian Online memes?
I love the "probably illicitly" part of that quote. The Sun will probably rise tomorrow. I should also note that when the couped-in "Government" came to power, they appointed three Governors: Taruta, Kolomoiski, and Saakashvili. Taruta's Donetsk is now in full revolt, (and being quite successful,) Saakashvili failed to prosecute a single corrupt individual in Odessa and lost even by Ukraine's corruption standards, and Kolomoiski was the Governor of Dnepropetrovsk, aka Dnipro.
So, NSG - what does Ukraine's couped-in "Government" has to do to lose your support? What do you think about this assistance to North Korea?
