A tunnel with no light at any end

Israel has re-entered the Rafah "refugee camp". Again it seems the IDF is looking for tunnels used for smuggling weapons.

These tunnels end in Gaza. Obviously a dark place by any standard. No light there.

But tunnels have two ends. Or a beginning and an end. No one ever talks about where the other end of these tunnels is placed. It is no secret though.

Weapons and explosives are smuggled into Gaza from Egypt, sometimes directly from an Egyptian Army base. A country formally at peace with Israel since 1980. A country from which a civilized person might expect real action to combat the type of atrocities perpetrated against Israel, with weaponry that could only be aquired with Egypt's acquiescence, if not active participation.
As has been clear for a long time, Egypt is still an active enemy of Israel in all but name.
(Check here and here for more on the tunnels).

This is not surprising, or at least, it shouldn't be. The absence of overt hostility is about the best a Jew can expect for giving back land conquered three times in successive defensive wars.

So what can Israel expect should they give up Gaza? Or Judea/Samaria? Or the Golan?
