There's a bit more to it than just going faster. The French, Japanese, Germans and others have spent a long time perfecting high speed technology. Current US passenger speeds (outside the NE corridor) are lower than 100 years ago - most US development has been in the field of freight, and no-one does that better. I don't doubt that American first could do it, they would just be playing catch-up if they weren't able to leverage existing expertise in some way, and the last thing American HSR needs right now is too much learning on the job - it's got to prove that it can be delivered on time and budget first time. There's a huge advantage if existing designs and practice can simply be copied from European or Far East practice.
In any case, this plan is just a response to a call for expressions of interest. It's just by far the most detailed and comprehensive of the documents submitted. It's main interest is as a sanity check for the administration's HSR plans - if SNCF thing it's doable, it probably is, and if they think it will have such great payback, then it won't be a money pit...
So, no offence intended, I should know better than to imply that the Americans can't do everything better than everyone else with no experience- exact opposite of us Brits by the way, who always assume that everyone can do everything better than us, even if we invented it (well it's true of Railways, Soccer, Cricket...).

Thats just the American way......we say we can when we know damn well we cant. Why play 30 years of "catch-up" when the French have been running the TGV for the last 30 years and know how do things right the first time
Skip the middle man and get to it!
