It's very hard to estimate the number. US still has the US Dollar, AI, most tech companies and entertainment industry as well as a lot of what I listed above still even though it's been reduced. Texas is becoming a green energy hub and California is still continuing the transition
Trump is working hard on the USD though by attacking the reserve and running an insane deficit and you can see treasury yields climbing. I would estimate that the USD dollar and military exports are more than 20% each. The leverage that US has on countries just by deciding who to sell and not to sell army stuff to is massive. Also having the global reserve currency and being able to largely cut countries off from foreign currency and banking is huge as well.
