Between China and the US, China is not the one currently burning bridges around the globe. US hegemony relied on mostly positive relations and power projection (both soft and hard). Scrapping our soft power and trading it for a bigger stick that's also being threatened with dismantling is unlikely to help the US retain its hegemony. Not to mention the military is an expensive stick and the cuts to revenue will result in even bigger deficits if it's maintained at its current level.
Regardless, it would be indefensible as a negotiating tactic. We're not cavemen.
