President Trump acknowledged on Thursday that there was a significant risk that Israel could soon attack Iran, but he said that “I don’t want them going in” at a moment when progress was being made toward an agreement to shut down Iran’s easiest pathway to building a nuclear weapon.

If there is military action by Israel against Iran, it would most likely be without U.S. support, sources said.

U.S. officials have been told Israel is fully ready to launch an operation into Iran, multiple sources told CBS News.
