The premise of collapsing the worm hole was introduced in the episode The Search Part II; and it was all a dream induced by the Founders. So it is possible that collapsing the worm hole is only possible by the Prophets or Pah Wraith's.
If that is the case, then Sisko had no choice but to go into the worm hole.
That the Prophets destroyed the Dominion fleet was done by the pleas made by Sisko. He won them over
I would also assume that since no second, equal or larger sized fleet, Dominion fleet attempted to cross the worm hole could mean that the Prophets denied the Dominion access to it.
That make any sense?
