Poland’s President Andrzej Duda proposed the United States build a military base in the Eastern European country. Duda offered to name the military base “Fort Trump” and has announced Poland will make a generous donation for the base’s construction.

The Polish government offered to spend over $2 billion for “Fort Trump’s” construction. An anonymous Polish government official, confessed to the Washington Post that Warsaw would also be willing to increase their donation over time, in order to further incentivize the Trump administration.

“Poland is willing to make a very major contribution to the United States to come in and have a presence in Poland. If they’re willing to do that, it’s something we will certainly talk about,” said President Trump during his joint press release with President Duda. While the Trump administration did not immediately promise to broaden its military presence in Poland, he assured the proposal would be “seriously considered.”

Currently, the United States has military bases set up in Germany, Greece, Britain, Portugal, Italy, and Spain. And Duda wants his nation to be the newest addition to the list. US forces are already deployed in the Eastern European country, in an effort to increase defenses on Eastern Europe after Russia’s 2014 invasion of Crimea.

Military Times reported the United States has been deploying the 173rd Airborne Brigade Combat team in a rotative manner. The Air Force also deployed five F-22 Raptors and 40 airmen in August, to set in motion joint exercises between the two militaries. A permanent military base in the region, however, would be a major step-up for the country.

A US military base in Poland would be a reassurance for the Polish government, as well as the world, that the US still accepts Poland as one of its key allies. The Eastern European country has been attempting to enlarge the US’ military presence in their country for over a decade, according to the Military Times.

The written proposal for the US’ permanent military presence in Poland suggests “Russia is seeking to strengthen its political and economic relations with key European countries at the expense of US national interests.”

The proposal later continues to support, “An increased US permanent presence in Poland will give America the strategic flexibility it needs to confront and deter these threats. It will help secure American interests it shares with its European partners in the region and preserve western values of freedom and democracy.”

Defense Secretary, James Mattis, however, has stressed that various details need to be analyzed before the United States can promise permanent military presence in the country. “It’s not just about a base,” Mattis told reporters, Reuters informed, “It’s about training ranges, it’s about maintenance facilities at the base, all these kind of things.”

Other topics covered throughout Duda and Trump’s meeting on Wednesday included defense cooperation and Poland’s disposition to increase natural gas imports from the United States, the Washington Examiner confirmed.
