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.

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

We don't tolerate terrorism. We go after the terrorists and those who support them and those who justify their actions.

The Iranians know what they need to do in order to become a responsible member of the international community and in order to become a good neighbor, and it's really up to them to change their behavior.

The war in Yemen is not a war that we wanted. We had no other option - there was a radical militia allied with Iran and Hezbollah that took over the country. It was in possession of heavy weapons, ballistic missiles and even an air force. Should we stand by idly while this happens at our doorstep, in one of the countries in which al-Qaida has a huge presence? So we responded, as part of a coalition, at the request of the legitimate government of Yemen, and we stepped in to support them.

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.

We have no interest in seeing an unstable Yemen or seeing a Yemen that is devastated.
