Putin said that "disrespect is shown for [Trump]" in the US, which he called "regrettable".
Russia's President Vladimir Putin speaks during a session of the Valdai Discussion Club in Sochi, Russia October 19, 2017.
Instead, he used a high-profile televised discussion with foreign academics in southern Russian Federation to reach back to what he regards as the darkest days of U.S. -Russia relations. "So it is not right to say that unpredictability is in his nature - it depends on the United States political system", Putin said. Speaking to an audience of foreign Russian Federation scholars, Putin said an unprecedented anti-Russia campaign was being conducted in the USA in which every domestic failure was being blamed on Moscow.
"Our biggest mistake was that we trusted you too much".
He added that he believed Hollywood had started using more Russian villains in films because the USA always needs someone to play "the bad guy". "And you have mistaken that trust for weakness, and abused our trust".
At the same time, he added that Russian Federation will remain open to cooperate with the United States.
He added, Russian Federation will abide by a landmark Cold War-era treaty as long as the US does.
The contest has not officially begun and Mr Putin has not yet declared whether he will be taking part in the March 2018 election.
"From our side, the response will be instant, and I want to warn, symmetrical", said Putin.
He said the United States had flouted nuclear and chemical weapons treaties, saying Moscow had diligently complied with the same pacts only to be repeatedly let down by the United States.
The comments contrast with earlier statements by Putin and other Russian leaders, who have said that a global ban on nuclear weapons is unrealistic.
"Old man Putin is so scared of our meetings in the regions that he decided to make himself happy with a small gift for his jubilee", Navalny said on Twitter after his sentencing.
