The risk of conflict is growing as Iran signals strikes on Israeli nuclear facilities despite ongoing nuclear talks.

Iran says it has no plans to build a nuclear weapon and is only interested in power generation and other peaceful projects. During his first White House term, Trump withdrew the U.S. from a 2015 deal between Iran and world powers that placed limits on Tehran's disputed nuclear activities in exchange for sanctions relief.

The president now confronts the reality that stopping Iran’s drive toward a bomb may require letting it continue to make some nuclear fuel.
