Actually the U.S. has _NEVER_ had the capability to support the
transportation for astronauts who live aboard the International Space
Station. It's relied on the Russian Soyuz since October 31, 2000.
The U.S. did have the capability to have astronauts _visit_ the space
station via the space shuttle, which it no longer has since the
retirement of the shuttle.
Visit vs. live is an important distinction.
Only the Soyuz has the ability to support long duration crews.
Whether or not crews flew to the ISS via the shuttle or Soyuz, the
long duration crews always relied on Soyuz "lifeboat" seats.
Per the 1998 inter-agency agreement the first 13 Soyuz lifeboats were
provided by Russia as in-kind contributions. 13 Soyuz x 6 months =
6.5 years. When the first space station crew launched on October 31,
2000 every partner knew that the Russian contribution to provide
Soyuz would end in April 2006 - that never changed and was never a
surprise to anybody who paid addition.
The U.S. was supposed to have its own rescue capability by that
point. At that point it was supposed to be a version of the X-38. If
that rescue vehicle was only certified to return crews from space
then the U.S. (including European, Japanese, and Canadian) crews
would still need the shuttle to fly to and from the ISS and only rely
on the X-38 for rescue if necessary. If the X-38 evolved into a
two-way vehicle it could fly crews to and from ISS and wouldn't be
dependent on continued shuttle operations.
The X-38 went over budget and added to ISS's increasing costs
resulted in its cancellation without any viable replacement
scheduled. That was the mistake - ignoring that the 2006 deadline
would not magically disappear.
The fact that the shuttle is not flying anymore has (almost) nothing
to do with the U.S. dependence on the Soyuz for transporting
astronauts to and from the space station.
Don't bring politics into it - Republican and Democratic
administrations and NASA administrators from Goldin to Griffin were
all very aware of the 2006 deadline and ignored that there was no way
for US segment astronauts to live aboard the space station.
