A White House spokesperson contended that “the onus for concluding this [nuclear] deal is squarely on Iran… Iran has raised a number of issues that has nothing to do with the mutual compliance under the nuclear deal. And that is where our focus and objective is. So, we would encourage Iran to focus on the deal negotiated in Vienna, rather than seeking to open issues outside the Vienna context or casting blame, of course, on others for a pause in the talks”.
