Donald Trump has never made a secret of his admiration for Vladimir Putin.
He called him “strong and decisive” in a recent interview.
Now, the Russian president is taking aim at the United States in a series of tweets, as the two nations face off in the first face-off between the two nuclear powers since the Cold War.
“I do not think it is fair to blame anyone but myself,” Trump wrote in a tweet Saturday.
“But I have a feeling the people of the United State have forgotten their own history.”
Putin’s spokesman Dmitry Peskov also took aim at Trump, saying he has “an interest in making the U.S. a stronger and more powerful power in the world.”
Putin is a longtime ally of the president, who has called him the “greatest” leader of all time.
The two men met at a G-20 summit in Hamburg in late July and have been allies ever since.
Putin has repeatedly called Trump “a friend” and praised him as a “fighter.”
Trump has denied the allegation, saying it is an attempt to distract from Russia’s alleged meddling in the 2016 U.N. election and hacking of Democratic National Committee emails.
The president also blasted the United Nations’ move to sanction Russia for the hacking and called the decision “politically motivated.”
The U.K. also launched an investigation into Trump’s claims about Putin.
