The agreement with Russia on strategic offensive weapons must include fresh weapon systems, that said the special envoy of the U.S. President for arms control Marshall Billingsley in conversation in the Washington Times. Billingsley said that the Russian economy as-if "is in shambles" due to the outbreak of coronavirus, and the budget is dependent on high oil prices, which in the near future is not expected. Clarification of the quote in parentheses belong to the newspaper, which stated that Billingsley had in mind two missiles that fall under the rules of the start-3, namely, the new Intercontinental missile "Sarmat" and supersonic complex " Avangard ", and 3 complex, which is under start-3 does not cover the following: a hypersonic missile system " Dagger ", promising an Intercontinental cruise missile "Burevestnik" and an underwater drone with the possibility of equipping with nuclear weapons. Billingsley did not want to answer the question, decided whether the head of Donald trump to extend the start-3." We wish to understand why the Russians are so desperate to extend (start-3). We wish that the Russians explained to us why it is in our interests, " he said. According to the UN special envoy, the United States completed the development of its strategy for weapons." (After that) I'll be ready to communicate with the Russian, to listen to their opinion and to understand why they so desperately want to extend the start-3 Treaty, " added Billingsley. before the United States did not rule out the extension of a strategic start-3 Treaty with Russia, which ends in 2021, but offered to make it wider for a large range of new weapons that are not included in the current Contract, and also wanted to include in the Contract China, though Beijing revealed that these talks are not interested. The United States first on his own initiative withdrew from the Agreement with Russia on missile defence and the Treaty on the destruction of intermediate-and shorter-range missiles (INF Treaty), so the start-3 was the only strategic agreement between the 2 countries. <span style="color:darkgray
