"I am convinced there is no more effective method of preventing a war than a decisive stance illustrating that we are ready at any moment to repel possible attack", Duda said. Duda didn't confirm the amount Trump stated. "The presence of the United States is a guarantor of security in our part of Europe". Duda offered to pay "billions" of dollars to defray the costs of the base, Trump said.
President Donald Trump speaks during a news conference with Polish President Andrzej Duda.
"We just think it's very unfortunate for the people of Germany that Germany is paying billions and billions of dollars a year for their energy to Russian Federation", he said.
A senior Polish government official said Warsaw would potentially be willing to spend even more over time or offer additional incentives to Washington. US forces now serve in Poland as part of NATO's back-to-back rotation program.
However, all the USA forces shuffle in and out of Poland and there is no permanent American base in the country.
Polish President Andrzej Duda, eager to secure a commitment, said his country would not only help pay for the facility but name it "Fort Trump".
Trump has been especially critical of Germany's defense budget and trade surplus with the United States, leading to tensions with Chancellor Angela Merkel.
On Monday, the US administration said it will begin to levy new tariffs of 10 percent on about $200 billion of Chinese products on September 24, with the tariffs to go up to 25 percent by the end of 2018.
The Pentagon, however, has said the United States remains fully committed to Germany.
Later in the event, Trump and Duda took questions from the audience.
Poland has repeatedly requested a permanent United States military presence on its soil.
"I am with the president".
"It is the reality that we live in today", Duda said.
Still, Poland's offer falls far short of replacing base arrangement the United States has in Germany, home to the massive Ramstein Air Base and major U.S. Army training grounds in the Bavarian towns of Grafenwoehr and Hohenfels.
Trump - accused by political opponents of having colluded in a shadowy Russian operation to aid his surprise 2016 election win against Democrat Hillary Clinton - agreed with Duda's assessment.
"I think it's a very aggressive situation", Trump said. "We just think it's very unfortunate for the people of Germany that Germany is paying billions and billions of dollars a year for their energy to Russian Federation", he said.
