I wonder wich history books or news sites you are reading cause they rewrite history as they go by.
73 was a clear israeli victory. From total suprise and chaos against all neighbours to close to the capital of the 2 mayor opposing states. Given a couple more days israel would have destroyed large parts of the arab armys.
2006 gaza: hundreds of hamas dead, barely any IDF
2006 lebanon :stalemate, or as bad for both partys
2009 gaza : hamas undermined seriously IDF gots its objective again with virtual no problems.
Turkey? Why would they attack israel ? Why not add the USA?
Egypt and syria stand even less chance then in 73 when everything went right.
