Russia was an important trading partner for many European countries. Especially important for Germany. Basically no sanctions. Freedom of movement with fairly good visa policies. No great internet firewall. How much did all this help to prevent another huge war between two European countries?
Different behaviors have different motivations, contexts, and causes. It's extremely clear that these, like other criminal moneymaking schemes in the DPRK, are directly and closely related to the high degree of isolation of the DPRK and the difficulty of getting capital into it.
Of course lifting the sanctions won't also end all spycraft, or ensure an end to geopolitical conflict. Those aren't things I have claimed or would claim.
And the primary reason to end such sanctions is not any benefit to imperialist nations but because of the fact that they inflict misery on ordinary people indefinitely and (not essential, but adding insult to injury) uselessly.
