In order to preserve a balance, while we aren't planning to build a missile defence of our own, as it's very expensive and its efficiency is not quite clear yet, we have to develop offensive strike systems. They [U.S.] should give us all the information about the missile defence, and we will be ready then to provide some information about offensive weapons.

My English is very bad.

I'd rather not deal with such questions, because anyway it's like shearing a pig - lots of screams but little wool.

You can do a lot more with weapons and politeness than just politeness.

We have a contract for the delivery of the S-300s. We have supplied some of the components, but the delivery hasn't been completed. We have suspended it for now. But if we see that steps are taken that violate the existing international norms, we shall think how we should act in the future, in particular regarding supplies of such sensitive weapons to certain regions of the world.

I believe it is no secret that I like Japan very much - Japanese culture, sport, including judo, but it will not offend anyone if I say that I like Russia even more.

There is nothing in common between al-Assad and ISIS, they fight against each other.
