Senator Schumer is meeting with Chuck Hagel this week in private. Schumer should consider that Hagel does not believe that a military option is an option even if negotiations fail.
He has recently changed his previous stated views on this issue to accept "all options are on the table", in order to advance his career. It means he now believes that it is expedient to use the threat as
a public lever in negotiations, but if negotiations fail, he would advise in private, that the US should allow a nuclear armed Iran.
Many of those who are in favor of confirmation such as Nicholas Kristof, writing in the New York Times, have said the same thing. Iran certainly understands this, and is rooting for him.
