During a press conference with the President of Poland, Andrzej Duda, Trump was asked whether he agreed with the opinion of his Polish colleague that Russia was a threat to Eastern Europe.
"I think this is a very aggressive situation. Russia is acting aggressively. They respect force, determination, like everyone else, "the US president noted.
According to him, the American side modernizes its army.
"We have, to put it mildly, strengthened our armed forces ... Hundreds of thousands of jobs are created by the best armed forces. Russia respects this, "he added.
In July, Trump said he had negotiated with Russian President Vladimir Putin in Helsinki in "a position of great strength."
