WASHINGTON, September 12. /TASS/. Washington’s declared goal of inflicting a strategic defeat on Russia is impossible, Russian Ambassador to the US Anatoly Antonov said, commenting on the US government’s remarks about the possibility of lifting restrictions on the use of US-supplied weapons for attacks deep inside Russia.

"The United States is steadily driving itself deeper into the quagmire of the Ukrainian conflict," he said, adding that the US government is "ready to sacrifice the well-being of US citizens by transferring multibillion-dollar volumes of weapons and ammunition to the Kiev regime."

"The only demand of Washington curators is to increase military clashes with Russian troops. We continue to be tested for the limit of our tolerance or patience to hostile steps. The overall purpose is the notorious strategic defeat of our country," the ambassador continued.

He went on to say that the US administration "stubbornly ignores Russia's interests."

"Now they are increasingly talking about the possibility of shelling Russian territory with long-range weapons. Only a few politicians mention the possibility of a Third World War to which local authorities are paving the way," the ambassador said.

Antonov reiterated that "it is impossible to negotiate with terrorists."

"No schemes or so-called ‘peace initiatives’ to cease fire in Eastern Europe without taking into account Russia's national interests are possible," he said.
