In the attached story, the Israeli spokesperson makes the claim that this means the UN is recognising Hezbollah.
But I don't think so. I have read lots of UN Reports about lots of groups, from Sendero Luminoso to ELN in Colombia, to Maoist rebels in India a number of years ago.
Even if a group has no status whatsoever, anywhere, it is the UN position that they should commit to the most basic human rights, such as no torture, no enforced disappearances, no execution of combatants hors de combat, etc.
Obviously, if these groups fail to meet a decent standard, it provides ammunition for the other side to try to avoid its own responsibilities. One can see this in the US today, where spokespeople say that Al Quaeda doesn't accept the Geneva Accords, so we don't hafta, either.
But compliance is an absolute requirement, not contingent on what the enemy does.
