The report was very clear about that. In fact it was included in the paragraph I posted that you think you wouldn't have chosen:
"There is no dispute that tunnels exist to smuggle contraband, including small arms and explosives used by Palestinian armed groups, into the Gaza Strip. But despite the tremendous burden that demolitions have imposed on the civilian population, the IDF has failed to explain why non-destructive means for detecting and neutralizing tunnels employed in places like the Mexico-United States border and the Korean demilitarized zone (DMZ) cannot be used along the Rafah border. Moreover, it has at times dealt with tunnels in a puzzlingly ineffective manner that is inconsistent with the supposed gravity of this longstanding threat."
http://hrw.org/campaigns/gaza/Now, if you want to try to argue that the report didn't say that the IDF exaggerate and mischaracterise the threat from tunnels in order to justify home demolitions, you'd be wrong. Again, I'd already posted this bit, but it looks like you ignored it.
"Based on interviews with the IDF, Rafah residents, the Palestinian National Authority (PNA), members of Palestinian armed groups, and independent experts on clandestine tunnels, Human Rights Watch concludes that the IDF has consistently exaggerated and mischaracterized the threat from smuggling tunnels to justify the demolition of homes."
As for the obligation of the IDF under international law:
"Under international law, the IDF has the right to close smuggling tunnels, to respond to attacks on its forces, and to take preventive measures to avoid further attacks. But such measures are strictly regulated by the provisions of international humanitarian law, which balance the interests of the Occupying Power against those of the civilian population.
In the case of Rafah, it is difficult to reconcile the IDF’s stated rationales with the widespread destruction that has taken place. On the contrary, the manner and pattern of destruction appears to be consistent with the plan to clear Palestinians from the border area, irrespective of specific threats."
and
"It is based on the assumption that every Palestinian is a potential suicide bomber and every home a potential base for attack. Such a mindset is incompatible with two of the most fundamental principles of international humanitarian law (IHL): the duty to distinguish combatants from civilians and the responsibility of an Occupying Power to protect the civilian population under its control."
This is all in the summary of the report itself. As for the recommendations of the report:
"This report recommends that the Israeli government cease its unlawful demolitions, allow displaced Palestinians to return, pay reparations to victims, pay to repair unlawful damage, and address the emergency needs of the displaced. The international community, which funded some of the infrastructure destroyed by the Israeli military and continues to pay for emergency relief, should press Israel to take these steps. In the meantime, if donors allocate funds to rehouse victims and repair unlawful destruction, they should demand compensation from Israel."
Not quite sure how you read that particular report so that yr reading something different into it than is actually there. I already asked you what two paragraphs you would have chosen. I'm not actually seeing anything in there that you could post as evidence to support yr claim that every home demolished in Rafah was covering a tunnel..
