We're within years of China's navy being able to take on the entire USN directly and coming out completely on top. A blockade would just be smashed. American proclamations of 2027 being a key inflection point are actually very indicative of what their own internal projections show about their own ability to resist Chinese military force. The theory is that this is when the US military will be at its relative weakest point vis a vis China, and that they'll massively recover military strength from early 2030s onward. My own theory is that this is nonsense and their decline will in fact accelerate starting from 2027, led in large part by further fiscal deterioration. In fact, we're already seeing the early signs of that this year. The input cost increases and rare earth magnet scarcity for their military industrial complex will have a net effect of throttling their military production, even if they manage to pull off large and consistent war budget increases. Instead, that extra funding (if they manage to do so) will just be wasted and corrupted away to an even greater extent than they do now. In short, even if they grow their budget bigly every year, it'll have massively diminishing returns in output. Their problem is not and has never been an inadequate budget. The real problem is inefficiency and corruption. And I'm just not seeing any real effort to address that. To fix it, they'd have to start by permanently closing the revolving door between senior military leadership and military corporations, ban military corporations from the right to lobby congress, undo the privatization in that sector that has occurred in the post-WW2 era, and reverse the big mergers that have happened in their military industrial complex in the post-WW2 era.
In other words, absolutely impossible and not even worth considering. Better to just get in on the financial action, which is what everyone is doing anyways.
