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.

Trump's Ukraine policy shifts from strong support to softer stance in recent weeks, reversing tough UN summit rhetoric as Russia war continues.

US President Donald Trump on Sunday said that, as of now, is is not planning to provide Ukraine with long-range Tomahawk cruise missiles to counter Russian aggression

Zelensky, due to visit Washington this week, wants long-range missiles to hit back at Russia - and Donald Trump says he may send Tomahawks.

U.S. President Donald Trump says he is not considering a deal to transfer Tomahawk missiles to Ukraine, citing fears of escalation with Russia.

The comments came as Trump’s growing frustration with Moscow after months of failed efforts to broker a ceasefire between Russia and Ukraine.

Lutnick’s remarks came as the Supreme Court began hearing challenges to Trump’s use of the 1977 International Emergency Economic Powers Act (IEEPA) to impose sweeping tariffs.
