the unifil wasnt sent to lebanon to enforce resolution 1559. it was sent to lebanon in 1978, based on resolution 425 to guard the withdrawal of israeli troops from lebanese territory. but you are partialy right, unifil was back then ordered to help the lebanese government to regain authority. but in detail that only means, that they are a kind of a referee. they shall report to the un who stepped over the lebanese/israeli border first in case of a combat. nothing more nothing less. so all this talk of they didnt do their job right, so its their own fault they might die, is totall cynical bs, even from a factual point of view. are you saying the same about american soldiers dying in iraq? i bet you dont..
