I did not answer it because it is a "might", not a certain thing. Also, take into account the fact that they knew it was a temporary thing when they came to the US. Now, knowing one possible outcome, they could emigrate to a third country that is willing to receive them.
And speaking of it is safe to return there, I am not familiar with what happens when the TPS status is removed, but I think it only means they’re no longer welcome in the US, not necessarily being deported to Somalia the next day. So I don’t see any contradiction.
Their TPS status was abruptly revoked and they were given two months to find another country to reside in or they will be deported to Somalia. Two months! Do you think that you could find another country to reside in and handle all of the legal arrangements within that short of a time frame?
I sincerely hope that you never find yourself in such a situation.
