Sure, they're helping an ally in a De facto war against Russia, but currently the us spends more on "defense" than both Russia and China combined, when it is technically at peace. In case of a war with China, are you expecting the military budget to not increase at all?
This is the problem with mitary and security infra of any country. They keep the bogeyman alive because their paychecks depend on it.
EDIT: At least here in Western Europe, we mostly have a supply side inflation, because energy got a lot more expensive, not because the government has been "printing" a lot of money. I suspect it's the same in the US.
But here in the USA, people like to believe it must be political and local, completely unrelated to the totally-coincidental worldwide issue that happens to be very similar.
Cool, whats your prognoses for effectiveness of the Reduce Inflation Act
But I suspect that subsidies for infrastructure is one of the least impactful factor for inflation.
