On August 15, Mariusz Błaszczak, Minister of National Defense, and Michael Pompeo, U.S. Secretary of State, signed an agreement to strengthen the permanent presence of U.S. troops in Poland. The agreement was signed in the presence of the President of the Republic of Poland Andrzej Duda. The agreement sets the legal framework for the presence of U.S. troops in Poland. The adopted principles are based to a large extent on regulations common to all NATO members, i.e. the NATO SOFA agreement of 1951, which Poland adopted with its membership in the North Atlantic Alliance. The agreement, which replaces the existing agreement from 2009, has been concluded for an indefinite period, and both parties can terminate it after informing the partner. This article details the provisions of the new international agreement, comparing its provisions with the existing legal regulations in the field of Polish-American cooperation.
