The waqf has a say only by the good graces of Israel - its a privilege not a right. (and a right that is often abused) and anyways I'm sure the waqf will understand Israel's decision, the waqf have a nice long history of unilateral decision making on the temple mount. But... I have an idea that will solve all the problems: The waqf will agree to take full moral and economical responsibility to anything that happens due to the structural soundness of the bridge. If they agree to fully and publicly indemnify Israel perhaps we can come to a happy solution?
