We've invested a huge amount in the QEC carriers and all the aircraft that go into Carrier Strike. That's power projection. Not at the scale of WWII but incredibly potent and mobile nonetheless. We also have (and will likely retain) the Continuous At Sea Deterrent. That in itself displaces the similarity between our Navy in times gone by and what it is today. We have T45 - an amazing capability (engines aside - yup, go fix it quick).
Forgive me if I don't share your doom and gloom, considering the world we now live in.
