In a move certain to agitate Russian nationalists, Poland has signed an agreement allowing the U.S. Air Force to base warplanes and transports in Poland. Thus, within two years, the U.S. plans to have F-16s and C-130s stationed in Poland. This is seen by Poland as a further protection from Russian pressure and threats. For over two centuries, Russia has regularly threatened, and often seized parts of, Poland. Russia is not happy with anything that might prevent more such moves in the future. Since the United States is a nuclear power, Russia will be constrained from moving on Poland as long as American troops are stationed there. But the Russians will definitely not like it, and this pleases the Poles a great deal.
