Well, we know can't be to "save America from bankruptcy" because as a currency issuer, the federal government of the USA can't go bankrupt the way a currency user like a corporation or state government might.
By cutting spending on foreign countries the US is forcing these countries to turn elsewhere for aid which will come in the currency of the new provider and with strings attached. This can cause a domino effect which will significantly weaken the USDs standing and force the US to take up "real" debt.
DOGE could very well bankrupt the USA if they aren't careful. They don't seem careful or self-aware.
