Washington D.C., United States—U.S. President Donald Trump has said that the Pentagon is considering the installation of a permanent military mission in Poland.

Previously during a White House meeting, Polish President Andrzej Duda had requested from President Trump the building of a new, permanent U.S. military base on Polish soil. He argued that this would serve as a deterrent and bulwark against Russian aggression. He proposed that is should be baptized “Fort Trump.” The Polish head of state even proposed to donate more than $2 billion for the funding of the project.

Both presidents said that Russia has been acting aggressively in the region. They cited the examples of Georgia (2008), the Baltics, Crimea, and Ukraine.

“We’re looking at it very seriously, I know Poland likes the idea very much, and it’s something that we are considering, yes,” said Trump.
