63% expected, as a result, Iran-backed terrorist attacks on United States soil. In my view, that outcome is actually highly unlikely, though it can't be ruled out. Iran has never been responsible for much terrorism on US soil. There was an alleged plot against the Washington, DC, Saudi embassy (what kind of horrible person kills someone in an embassy?) But large states with conventional militaries do not usually resort to terrorism -- it is the weapon of non-state actors in the main.
62% said that Trump's drone strike raised the chances that the United States and Iran would end up in a war. I think the US public is wiser than Trump on this issue. He seems to think he can keep strangling the Iranian economy and hitting Iran hard without any risk of war at all. That isn't the way the world works, and there is always a danger under such conditions of events spiraling out of control.
