Yep and Obama knows it - his plan is to keep up the charade with us and our allies right up to the point where Iran will have the means to take out Israel.
If you give the Iranians enough time, they will freely give a nuke to ISIS and have them detonate it in New York City.
This is why I think Israel will strike soon or immediately after the next presidential election. Especially, if Hillary or Sanders seize the white house.
