Years of miscalculations by US/NATO led to dire shell shortage in Ukraine

thats not a miscalculation. these miscalculations are precursors for fast track productions and deliveries, which makes two things possible:

a) the shortage creates a dire straits scenario, a crisis, an imminent combat ineffectiveness but then the fast track deliveries from the saviors arrive ... and ding ding goes the bell, next rounds' on us

b) lords of war get to smuggle loads of stuff into the middle east et al. In a war torn country, especially the most corrupt country on the continent, nobody can expect proper order in logistics and stuff, "fuck your checks, our men are about to get fucked by Ted the fucking Teddy Bear that Matt Wahlberg made a movie with. They need Ammo!", an obviously American man in his thirties said, trying really hard to fake a Ukrainian accent(?) ...

oh, and higher costs of course, paid by NATO, with promises and commitments from the Ukrainian side, who are of course, eternally grateful
