Indeed it is. I don't agree with what Israel is doing but I've said it a few times on this thread, I'd challenge anyone faced with a similar threat to act differently.This is the horrible conundrum Israel faces. Going after Hamas the way they are, and killing what they consider to be an 'acceptable' number of civillians for every terrorist, is in danger of reducing them to the same level as the terrorists in the eyes of many. Horrible situation.
If Manchester was attacked and thousands were killed in one swift terrorist act followed by continued attack every single day then would everyone be calling for a ceasefire and restraint? No. They'd first and foremost want the maximum amount of force to be used to stop the threat.
There is a question as to how effective Israel has been in stopping that threat and the subsequent civilian casualties but I don't see any alternative. They can't stop and do nothing whilst the attacks continue and there just is no other alternative.
The only way out is to negotiate a ceasefire with the Hamas leadership but that leadership is backed by other states who want this to carry on for as long as possible because they did after all instigate this for a reason.
