Great episode, but was it really wise or ethical to destroy the worlds main defense? O'neill kindof waved it away saying that the Goa'uld didn't know the hammer had been destroyed, but judging from the fact that Uran has managed to keep himself alive for who knows how long seems to indicate that once in a while some Goa'uld, like Kendra herself did, still come through. And once one has come through the game is basically up. Blocking the exit wouldn't really help much against the energy staffs blast imho.
And with the staff working it seems to me that they could have just blasted a hole in the rock around the hammer gate that could have been blocked after. Without being able to go through the hammer gate an energy staff wouldn't work in reopening that hole.
