A White House spokesperson put it the best, I think:
The White House spokesperson Andrew Bates, when asked about Trump’s comments, said: “Encouraging invasions of our closest allies by murderous regimes is appalling and unhinged – and it endangers American national security, global stability and our economy at home.”
What’s so insane about all this is that Trump saying something like that out loud means it’s now practically gospel to the vast majority of GOP voters, and might as well be official party policy.
Being able to supply another country with weapons and ammunition while keeping enough stock for your own military is not the definition of a self-sufficient military, though?
If we were able to succesfully do so, I would agree with that. We aren’t succeeding in supplying enough to keep Ukraine in the game right now, though.
The point is that having any ammo left over for Ukraine at all – let alone “enough” – is literally the definition of more than self-sufficient.
