If you go to the artillery shell store and there ain't no artillery shells, that's where an artillery shortage comes from.
BTW - we all know that the US was sliding arms and ammo to the Ukraine under the table before the DC establishment passed the bill to make the under-the-table stuff legal.
So, that was all "paid forward" beforehand.
Nice try with your propaganda, though!
US stopped sending artillery shells to Ukraine for months due to lack of funding, not because of shortage.
Czech Republic found 500,000 155 shells they can buy from third party sources. I guess the "shell store" wasn't empty.
Czech President Petr Pavel said at the Munich Security Conference last month that his country had identified 500,000 rounds of 155mm shells and 300,000 rounds of 122mm ones that could be delivered within weeks if the money was made available.
