It could be a tragic mistake,if Israel,because it's going to have American support,will depend too much on the Americans, & less on her own National Interests first & formost. America's interests doesn't always coincide with ours. In a fast & changing situation,be it a huge terror attack or any unforeseeble situation America will deal first of all for her country. In that case,if Israel were to put too much emphasis on America's backing,it could turn out to be a strategic mistake. Israel has to plan all her moves for herself & by herself. To get help is another matter,but not to conjoin the two forces. It's human nature. When you think you have a big & powerful ally you inadvertently depend on him more than it's heatthy for your own sake.
