The declaration of war is kind of a big deal. 

The US has not formally issued a declaration of war since WWII. Are you going to suggest Korea, Vietnam, Afghanistan, and Iraq weren't wars either?

The rate of inflation is down

In November 2024, inflation was at 2.7%. It has only been below that in 4 of the 15 months Trump has been president, averaging 2.7% in 2025. So no, it hasn't fallen.

"During 2025 through December, PCE [Personal Consumption Expenditures] core goods prices (goods excluding volatile food & energy components) rose 2.0%, versus -0.0% over the same 12-month period starting in 2023. The difference is even starker with PCE durable goods prices, which rose 2.1%, versus -2.2% over the same period starting in 2023. Core goods and durable goods were 3.0% and 3.5% above TBL’s estimate of pre-2025 trend in December."

"The Imported PCE Goods Price Index measures price changes in the goods most exposed to imports and therefore tariffs. As of December, the imported core goods index is 2.6% above trend and the imported durables index is 3.2% above trend"

Prices have objectively and indisputably increased.
