Israeli IDF thwarted again

Israeli IDF thwarted again by the audacity of the Palestinian peoples.  Last night the IDF ordered the destruction of a home owned by wanted terrorist Mohammedweil Baroud .  As is usual in these situations, the IDF called in the warning to residents to evacuate the home.  Usually this is done, the home is destroyed (often the terrorist escapes) and the innocent civilians are saved.

In this situation a new strategy was taken by the terrorist, he fled to a nearby mosque and called on friends and family to act as HUMAN SHIELDS on his home.  The IDF called off the strike to avoid killing 'innocent' civilians.

Palestinian terrorists called this action a great victory, thwarting the attack and promised this will now be an ongoing strategy.

The question is why the IDF call in these warnings? why do they give the opportunity for escape and further embarrassment to the military effectiveness.
