Israel was not seeking to topple Hamas. Israel and Gaza have seen this before. This is the fourth conflict in Gaza since Israel disengaged from the Strip in 2005. And Israel, in the same time, attacked Hamas military assets in the Strip including, notably, the underground network of military tunnels. And the fault line is, again, Jewish and Arabs.
Gaza is involved in the Middle East.
