Israel's fight with Hamas won't effectively take out Hamas, just as
Israel's fight with Hizballah didn't effectively take out Hizballah.
To truly root out Hamas from the Gaza strip, Israel would have to
arrest and imprison every young Palestinian male living in Gaza, so
that Hamas won't be able to simply recruit new grunts to replace
the hundreds killed by the IDF.
Ultimately, Israel doesn't care about Hamas, but about Hamas'
ability to acquire missiles and shoot them into Israel, and its ability
to send suicide bombers into Israel.
Israel placed the Gaza strip under siege in order to try to keep
missiles from entering the Gaza strip and suicide bombers from
coming out of it. Although the latter goal was reached, the former
wasn't because of missile-smuggling tunnels dug underneath the
border between the Gaza strip and Egypt.
What Israel has to do is place steel and concrete barrier-walls
underground all along that border, to block any tunnels.
The problem is that no matter how deep Israel buries the barrier-
walls, Hamas will simply dig the tunnels deeper, so as to go
underneath the barriers.
To prevent this from happening, Israel would have to have control
over every house, every covered location within Gaza from where a
tunnel into Egypt could be started.
But Israel isn't interested in permanently occupying every last inch
of the hellhole of the Gaza strip. Such an occupation would result in
a slow, cruel, war of attrition whereby IDF soldiers would be killed
and captured regularly by Hamas guerrillas.
In lieu of occupying the Gaza strip, in order to prevent tunnels,
Israel would have to have control over every house, every covered
location on Egypt's side of the border.
But Egypt won't ever permit Israel to have control of any part of its
territory, and probably will balk at a U.N. force controlling any part
of it either.
Egypt could say that it will "step up its measures" in combatting the
tunnel operations on its side of the border, but the Egyptian military
and police forces could get slack and stop checking every house and
covered location regularly, or start taking hefty bribes from Hamas to
look the other way.
Another problem is that tunnel operations within houses can be
hidden if there's enough warning of an impending inspection of the
houses. Hamas could buy through bribes enough people within the
Egyptian military and police forces to give Hamas a heads up of
where inspections are planned to occur. Hamas could then clean the
dirt out of the houses where tunnel openings are and place plywood
and rugs over the tunnel openings to hide them during an inspection.
What Israel could do to locate any tunnels that have breached the
border is to fly helicopters with powerful ground-penetrating radar
along the border daily. But these helicopters could be shot at by
Hamas guerrillas so that they crash and burn.
So there's really no foolproof way for Israel to keep tunnels from
continuing to be dug.
Even if the U.N. agrees to get heavily involved in patrolling the
Gaza strip and and searching for tunnel-operations on both sides of
the border, Egypt and Hamas probably wouldn't agree to any real
U.N. control over the Gaza strip or border area. And if Egypt agrees,
and Hamas is forced to accept U.N. control of the Gaza strip, all
Hamas would have to do is blow up the U.N. headquarters in the
Gaza strip with a truck bomb, and the U.N. would withdraw its
presence there, just as the U.N. withdrew its presence from Iraq
after the blowing up of its headquarters there. (The U.S. could have
secretly arranged for that, in order to be left in sole control of Iraq.)
So Israel ultimately will be left alone with its Hamas problem, and
there's no way to resolve it. It's like an inoperable cancer that
comes back again and again no matter how drastic the treatment.
The best Israel can hope for is to contain Hamas within the Gaza
strip, and slow down Hamas' rearmament.

chapters 38-39 requires that it will happen before the millennium.
