“If Ukrainians have asked the whole world to be all in for democracy, we need them to be all in for democracy,” said Waltz. 

“And they certainly have fought bravely and they certainly have taken a very noble and tough stand. But we need to see those manpower shortages addressed.”

IMO: Ukraine does need to address manpower shortages. But it’s not only shortages; it’s about quality, including training and arming as well as other related issues that it needs to address. As for it being “all in,” I can’t think of anyone who’s been more “in” for democracy in the past three years than Ukrainians.
