Two astronauts stranded for nine months taking the ISIS supplies intended for others. This is after they safely docked, which was considered risky at the time.
We had two astronauts stranded in space for the better part of a year just last year!
Except you forgot to mention an epic leak in Destiny just three years after it was attached to the ISS: "At its highest rate, the station was leaking about 5 pounds of air per day overboard." [0] Imagine that happening on the 4th year of American Mars mission.
Also, if you on American mission to Mars, it would be reasonable to worry about cooling system dying mid-flight requiring three spacewalks to fix it: "We'd lose cooling capability to half of the electronics on the U.S., European and Japanese part of the space station." [1]
The Soyuz, the MIR, the human space records, the Venera program, closed cycle rockets, all have no equivalent in the West. Even their version of the shuttle was superior (it flew 100% autonomously).
I don't like Musk, but he single handedly saved the Western space programs.

They've also got some new passenger jets certified and about to enter production (MC-21 and SU-100).
