USA's pull-out from START-3 to trigger massive arms race

During a debate in the 2016 presidential election, Trump said Russian Federation had "outsmarted" the United States with the treaty, which he called "START-Up".

In 2001, Slovenia hosted Putin's first meeting with former U.S. President George W. Bush that led to a short-lived thaw in relations between Moscow and Washington. After removing his hand from over the mouthpiece of the receiver, Trump told Putin New START was a bad deal negotiated by President Obama and that the treaty favored Russian Federation.

During his confirmation hearings, Secretary of State Rex Tillerson said he supported the New START treaty and reiterated the importance of staying "engaged" with Russian Federation.

Julianne Smith, a Russian Federation expert at the Center for New American Security in Washington, said the story-if accurate-demonstrates the danger of Trump holding foreign policy calls before being briefed by government experts.

What is more concerning is that the treaty Trump denounced is considered a key step towards reducing and monitoring both countries' deployed nuclear weaponry.

Putin and Trump have both said they hope to try to improve U.S.

He now runs an eponymous center that's created to be "a platform for an informed debate on global issues", and said he hopes Trump studies up on the issue before he talks to Putin again.

A Republican senator who played a key role in passing the last nuclear treaty between the USA and Russian Federation said he was "worried" about President Trump's apparent lack of knowledge on the topic - and wishes he'd study up.

On Donald Trump's first official call with Vladimir Putin recently, the new president apparently didn't know what the New START Treaty with Russian Federation was, but that didn't stop him from immediately declaring it a bad deal that was unfair to the United States.

The possibility of extending a pivotal Russia-US arms control pact is to be discussed in prospective talks with Washington, the Kremlin said Friday.

President Trump had another embarrassing phone call with a foreign leader - this one with potentially unsafe consequences. It is unclear whether Trump's national security adviser, Mike Flynn, briefed the president before he spoke with Putin.

He added that any concessions on which the START Treaty could be extended are hardly possible.

Granted, that seems plausible given how oddball some of his diplomatic engagement has been lately, but if Reuters is wrong about how much Trump knows about New START, there's no reason to believe the other key details. All of which raises the question of whether his opposition to New START is now fixed or whether it was just something he said in the moment to hide the fact that he hadn't studied for that day's test, so to speak, and was operating on the assumption that any deal Obama had agreed to must necessarily be bad.
