Answer is...it depends. Encrypting something 1000 times takes 1000 times longer to decrypt. As such doing something like this is fairly effective against brute force key guessing attacks, since it takes 1000 times longer to see if the current iteration of guessing is successful.
On the other hand if the algorithm it self has been cracked, no.
