Ukraine built up a 600,000 man army and it turned out they needed it.
NATO built the Ukraine’s 600K army to fight their proxy war against Russia. They still hope to trigger WWIII so they continue their proxy war - well that and the desire for more of that luscious tax payer money in the form of ‘foreign aid’ even though the Ukraine stands zero chance of winning - American dollars are always good to have for bribes and mansions.
they wouldnt have needed it if they stuck to the agreement they signed in 2014.
