Given that yearly DoD spending is at or near $750 billion, this is just 5 and a bit years of military spending for the USA. The USA also generally ups the DoD budget somewhat every year. One might think that because the DoD can't be audited due to extraordinarily messy financial systems, the DoD appropriations are actually lining someone's pocket, and the reason people piss and moan over non-DoD spending is that nobody gets to grift off it.
Biden has not called for drastic cuts in defense spending. I don't think "we spend a lot of money on X" is a good argument for "let's spend a lot more on Y".
