There are some interesting comments in Russia to Irans development of nuclear military capabilities. See this.
Izvestia calmly notes that Irans successfully tested Khaibar missile can deliver a 1.5 ton nuclear warhead over 2,000 km and has capabilities against electronic countermeasures. Izvestia then adds, that Iran can have a nuclear warhead in 2-3 years.
Also, Izvestia notes that there will be no JCPOA. On the prospects of this, Izvestia argues that a nuclear Iran is no cause for worry and will safeguard friends of Iran (of which Russia is one).
This news comes as reports emerge that Iran has completed a new nuclear facility which is 90 m underground out of the reach of even the US strongest bunker buster bombs. Neither JCPOA nor US-Israeli conventional bombs can stop the Iranian nuclear program. As Izvestia dryly observes, the Iranian military nuclear program has left the technical phase and is already a political reality.
