I can't see the point of the US maintaining the current state of overspend on the Pentagon and it's Pretty New Toys, unless it has some actual bearing on world security.

Umm, anyone remember a little maritime trade route hassle off the Horn of Africa a few months ago, because the US was so obsessed with its GWOT (Gumbo War of Terror) - largely against the Muslim world - it forgot its much more important role of maintaining the security of the trade routes? One of the major reasons why China keeps propping up the US Dollar? When, given the US near-universally vote-winning rant on the "threat" that the PRC poses to the US, it would be much cheaper for the PRC to start putting conditions on its dollar-buying spending sprees. Or simply dump the US Dollar and demand repayment in yuan.

As it stands, since most of that money goes into maintaining an obese military machine and its equally obese pork-barrellers in the US Congress and all 50 States, it hasn't affected the inefficiency of the US military machine at all.

It won't have any effect on the safety of the international maritime trade routes; it won't effect the eventual collapse of the US superpower status; and may do nothing more than accelerate its reduction to third-world beggar banana republic owned by the PRC.

Move along: nothing to see here.
