A battalion of 3,000 North Korean soldiers will shortly join Russian troops in fighting Ukraine, marking Pyongyang’s full entry into the war.
Intelligence sources said the unit has been secretly training in Russia’s Far East ahead of deployment as part of a Russian airborne regiment.
“They are called the Buryat Battalion,” a senior Ukrainian military source told Politico. Buryatia is a remote region of Russia bordering Mongolia that the Kremlin has targeted heavily for military recruitment.
The Kyiv Independent quoted another Western intelligence source claiming that North Korea had sent 10,000 soldiers to join the Russian army.
Honestly, no it's also done the opposite. Ukraine has passed so many of Russia's "red lines" that it shows nukes are useless too. The only time a nuke is useful is when you've already lost. If you use one then you get a lot of other groups attacking you, and potentially you get nuked yourself. You can't actually really use one in defence.
The only way to not be invaded is to be stronger than your potential opponents. Si vis pacem, para bellum. (If you want peace, prepare for war.)
