In CBO’s projections, the federal budget deficit in fiscal year 2025 is $1.9 trillion. Adjusted to exclude the effects of shifts in the timing of certain payments, the deficit grows to $2.7 trillion by 2035. It amounts to 6.2 percent of gross domestic product (GDP) in 2025 and drops to 5.2 percent by 2027 as revenues increase faster than outlays
"The budget projections are based on CBO’s economic forecast, which reflects developments in the economy as of December 4, 2024. They also incorporate legislation enacted through January 6, 2025."

IMO, 5%+ percent of gross domestic product (GDP) in a country with massive trade deficits is not sustainable.
