Your quote inferring that Obama did this alone is another in a long line of quotes you take out of context in an attempt to deceive people. You completely ignore the next line in this article which is:

"he said, referring to the apparently almost-finished nuclear agreement between Iran and a group of world powers led by the United States." A "group of world powers" is not one man doing it himself. 

And your assertion that only Muslims use the term "God willing" is beyond laughable.
