US attack on Iran is all or nothing - the regime will die fighting if needs be

Only thirty-six hours ago, Trump's envoys were meeting with a high-level Iranian delegation in Geneva to discuss a diplomatic solution.

The initial noises were positive. Conversations that I had with figures involved in those negotiations were optimistic that the sides were drawing close to a provisional agreement, although some obvious and significant gaps remained.

President Trump, with the help of Israel, is going for regime change. It's all or nothing.

Iran's ability to respond might be limited, following the attack on its ballistic missile sites last summer, but already strikes have been reported across the Middle East, not just Israel. The Iranian regime won't roll over; they will die fighting and will drag the region into a wider conflict if needs be..
