You only need to control the entry and exit node - since you know the next and previous hop for all traffic you touch, and default chains are 3 long. With circuits changing every 10 mins, within a few days you would have deanonymized at least some percentage of traffic for nearly every user.
I'd call tor broken against any adversary with a little technical skill and willingness to spend $5000.
I'm 80% sure Tor is designed as a US supported project to focus those needing anonymity into a service only governments with global security apparatus (who can grab a good chunk of internet traffic) can access.
