Israel has launched a ground invasion of Gaza, sending a column of troops and tanks into the Palestinian territory to destroy Hamas rocket launchers.
It is hard to think of a good ending to this. Israel does not want to reoccupy Gaza, but anything short of that is unlikely to destroy Hamas. I think they are hoping that if they destroy enough tunnels and cause enough damage, Hamas will collapse on its own.
But I think that this is unlikely. TV stars have a way of getting the money they need to survive. And right now, Hamas is a TV star all over the Arab world.
