Ukraine is fighting a war against two nuclear weapons countries: Russia, a signatory of the non-proliferation treaty, and North Korea, which is not. Since 2014, Moscow has been undermining the logic and letter of the Nuclear Non-Proliferation Treaty (NPT) with its nuclear posturing.

North Korean ballistic missiles fired at Ukraine by Russian forces since late December have been far more precise than salvos of the weapons launched over the past year, two senior Ukrainian sources told Reuters.

Though North Korean ballistic missiles account for only a small portion of Russia's missile strikes they carry a large warhead of up to one tonne and have a range of up to 800 km, the military source said. The Iskander-M, an equivalent Russian missile, carries a smaller payload and has a shorter range of 500 km.

Experts say Pyongyang’s advancing missile technology raises global security risks and threatens regional stability.

North Korean troops seem to temporarily withdraw from one section of front in Kursk Oblast, military says Russia claims to capture Velyka Novosilka, Ukraine admits partial retreat but says battles ongoing Russia intensifies attacks near Pokrovsk,

North Korean troops, largely special ops forces, have suffered high casualties in bloody assaults not unlike other units, including prison units.
