POLISH PRESIDENT PROPOSES PERMANENT US BASE CALLED 'FORT TRUMP,' DESPITE NATO RESTRICTION

The troops are part of the 21st Theater Sustainment Command (TSC) based in the Zagan region. They are part of a strategy to shore up NATO member Poland’s defense capacity at a time of heightened Russian military activity.

Last year, Poland’s defense minister said his country would be open to having thousands of American troops permanently stationed as a possible deterrent to Russia.

Later President Andrzej Duba told President Trump that if the U.S. were to create a permanent base in Poland, his country would pay more than $2 billion for the project and call it “Fort Trump.”

Duda emphasized that his country was "willing to make a very major contribution to the United States to come in and have a presence in Poland."
