The problem with today, is too many people are just willing to stand and watch bullying and not do anything about it.  Israel has the backing of most of the west and more importantly the US, hence they feel that they can do anything they want.  The US support them because they are the only ally and signigicant military base that they have in the Middle East.  Does that mean they can do what they want?  It seems that way.  And too many people like to watch, but not do anything about it!
