From Michael Paarlberg, lecturer in government at Georgetown University, writing in the Guardian:
Trump’s budget isn’t about saving money – he’s said so himself, that military spending is “more important” than a balanced budget. And it isn’t about rebuilding a “depleted” military for a country that already spends more on defense than the next twelve countries combined. Trump’s plan is about catering to his base. Not the fabled white working class, who will soon lose their WIC, heating subsidies, and job training. No, his real base, those golfing buddies and board members at companies like Lockheed, who want lower taxes and access to the government spigot, and want poor people to pay for it all.
It’s also about disciplining the deep state. Notably, the agencies facing the sharpest cuts are not the most expensive but those Trump has suspected of disloyalty: the EPA, state department and the USDA, all of which Trump’s transition team sought to muzzle and requested lists of names of employees working on programs he opposes.
Taken as a whole, Trump’s proposal points to an increasingly paranoid strongman who sees budgets as tools to reward friends and punish enemies, the military as a personal ornament, and poor Americans as piggy banks for his boondoggles and vanity projects.
