That's because this cult don't think about concepts like loyalty and human life - it doesn't even enter their brain for a second - their only argument is about money, and even that is wrong. They erroneously think that as some NATO countries don't meet the 2% GDP target spend on their military, that the US is somehow paying for this shortfall. As if it was like a subscription fee that they are subsidising. Obviously, that's not at all how it works, but they aren't exactly a brain trust.
They don't realise that the US voluntarily spends trillions on defence because it confers enormous economic and geopolitical benefits, and that they could reduce this drastically if they wanted to of their own volition - no, they think somehow this huge amount of spending is actually the other NATO countries' fault.
