What? Am I missing something?
Not from where I stand. That's an insane comment.
I think this was a mistake by the person who wrote the article. He was meaning to say that Congress and pro-Israel groups want the administration to soften their insistance on keeping the slow and very diplomatic approach and start getting tough. But by using the word "soften" it leads you to beleive that Congress and pro-Israel groups want the administration to go easier on Iran. Poor choice of words.
