As long as Iran's aggressive policies continue, it's going to be bad for the region. Iran has to decide whether it wants a revolution or a nation-state.

We want to have good ties with the Iranians, but if they want good ties with us, then I tell them: Don't keep attacking us as you have done for the last years.

Should the political process not work, there is always the other approach.

After the revolution of 1979, Iran embarked on a policy of sectarianism. Iran began a policy of expanding its revolution, of interfering with the affairs of its neighbors, a policy of assassinating diplomats and of attacking embassies. Iran is responsible for a number of terrorist attacks in the Kingdom, it is responsible for smuggling explosives and drugs into Saudi Arabia. And Iran is responsible for setting up sectarian militias in Iraq, Pakistan, Afghanistan and Yemen, whose objective is to destabilize those countries.

I don't think anyone can predict what the short term will look like. In the long term, it will be a Syria without Bashar Assad. The longer it takes, the worse it will get.

Is Russia worried that defeating Daesh will open the door for defeating Bashar Assad? That would be a different story. But I don't think World War III is going to happen in Syria.

Daesh members wear shoes. Does this mean everybody who wears shoes is Daesh?
