Russia has started combat drills with its military aircraft over the Baltic Sea to test their fighting capabilities and operational readiness. Meanwhile, Germany is preparing to deploy 4,000 troops permanently in Lithuania. Denmark is reportedly providing training to Ukrainian pilots to fly American F-16s. These activities indicate the escalating tensions in the region. The Baltic Sea, located between Poland and Lithuania, was part of Germany until the end of World War II. Germany’s deployment of troops in Lithuania could further increase tensions in the area.
