Less than a week into what is looking more and more like all-out war between Israel and Iran, the Iranian supreme leader sent a message of defiance. In a televised address, Ayatollah Ali Khamenei rejected US President Donald Trump’s call for Iran’s “unconditional surrender.” Trump was asked if the US would join Israel’s bombing campaign in Iran. “I may do it, I may not do it,” was Trump’s response. “I mean, nobody knows what I’m going to do.” It’s not clear what comes next. But as The World’s Matthew Bell reports, Israel has already demonstrated extensive intelligence capabilities inside Iran.
