The Gemara (Avodah Zarah 3a) says that Hashem will give them a second chance, for the very reason your student intuited: that it isn’t their fault.
It says he will give them the mitzva of Sukkos, so good timing on this one.
It also predicts that they will ultimately reject the mitzva. However, one would think that this prediction is not set in stone, for if it were, it would (ironically) entirely defeat the purpose.
