Israeli Prime Minister Benjamin Netanyahu said Tuesday he spoke in English when he dramatically outlined Iran's secret nuclear weapons program because he wanted the world to know what Israel spies were able to uncover.

"I wanted the world to hear it, all of it, and there are only a few million Hebrew speakers, and there a few billion English speakers," Netanyahu said on CNN Tuesday.

Israeli Prime Minister Benjamin Netanyahu "wanted the world to hear" his claim to have proof of a secret Iranian nuclear program, which is why he spoke in English.

"This is a very important subject which relates to our quest for peace and security in the Middle East and the world, and I thought it was important that the broadest audience possible would hear the dramatic findings that we found about Iran's secret nuclear weapons program," he added.

Netanyahu on Monday spent several minutes outlining more than 100,000 files that Israeli spies took from Iran that show Iran lied years ago when it said it was not pursuing a nuclear weapons program.

Supporters of the agreement from the Obama administration said his speech revealed nothing the world didn't know about Iran's intentions. But Netanyahu said the documents show the Iran deal was built on lies, and said Trump will have to decide by May 12 whether to stay in the deal.

He said later on CNN that "The whole premise that this deal somehow guarantees a safer, more moderate Iran is wrong."
