The US hasn't put as much in compared to Europe as they'd have you believe. Whilst Europe has sent fewer weapons, they've been supporting monetarily. And the US was sending stockpiled weapons, marking them at book value, and then reinvesting that money into US defence firms to buy new weapons.
And let's remember that most of the Ukrainian refugees have been hosted in Europe [1], something for which I am proud of being European. This has a monetary cost that Trump's administration seems to ignore when they keep saying that the US have spent far more than Europe to help Ukraine.
