By Tom Balmforth LONDON (Reuters) -Russia has in recent months attacked Ukraine with a cruise missile whose secret development prompted Donald Trump to abandon a nuclear arms control pact with Moscow in his first term as U.

In a televised meeting with his Security Council in Moscow on Wednesday, the Russian leader responded to the announcement that the U.S. would "immediately" resume tests.
