Except they aren't facts, certainly not as presented.
Consider, you state:
"blackmails the rest of the globe with nuclear deterrence"
Blackmail is the threat to expose something the victim doesn't want to see exposed, in exchange for some price or service. Nuclear deterrence, is just that, deterrence. Meaning to mitigate (or deter) an adversary from attacking.
"it ensures trading routes remain open" -- all nations with navies protect legitimate trade from pirates, there are ships from at least a half dozen navies protecting cargo from Somali pirates for example.
The US uses its intelligence agencies to undermine the constitution in the service of corporate interests [paraphrased, if you don't agree feel free to correct my interpreatation] -- The US certainly doesn't do this as a matter of policy, if you know of a different policy it would help your case to actually include it as a citation.
"it outspends the rest of the world on defense" -- In terms of real dollars or in terms of percentage of GDP? The last time I checked as a percentage of GDP, Israel outspent everyone else but I haven't looked in a while. There is also an economic size effect here, the US spends more (in real dollars) than any other country on social programs as well (for example). You probably want to stick to per capita numbers though if you're doing nation-state comparisons.
There are lots of things you can say about the US that are both facts, and make the country look bad, but the choices you made aren't facts so they have a hard time persuading the reader of your 'hegemony' thesis.
