No, western countries have been providing billions of dollars of loans to Ukraine each month to make sure that the country doesn’t completely fall apart. Most weapons provided to Ukraine by the US have been drawdowns of government stocks (which I doubt repayment for is expected, although I do not know the finer details).

Nah they’re true loans. When we give other countries money to buy weapons from us it’s almost exclusively grant money not loans, but for obvious reasons we aren’t even doing that step here. mostly the us is largely just dealing with the contractors directly

A large amount is not. Despite the meme that the USis only supporting the defense industry, they are doing a lot to help Ukraine through this. True economic and humanitarian aid has come in large numbers.
