- Gutting the Fed Gov doesn't bring down inflation or prices. These are not correlated issues.
- The US is a net exporter of oil, doesn't depend on the Saudis.
- "Giving Ukraine" to Putin won't happen, as much as Trump would like to help his buddy out, but because the EU won't let it, because Congress ultimately controls spending, not POTUS, and they're the ones (mostly the GOP) pushing for more military aid and a bigger budget (they upped Biden's military budget and aid to Ukraine). But even if Trump did drop all US military aid to Ukraine, the Ukraine won't just collapse, that would take time. And even if Russia did fully occupy Ukraine and "end" the war, that doesn't impact food prices in the US as food imports from the Ukraine are a tiny percentage of total food imports, very little impact. Sunflower oil, maybe.
These are not factors that will bring down prices.
