Poland, a country that lies on the eastern flank of the European Union (EU) and North Atlantic Treaty Organisation (NATO), is making serious efforts in defence to reorganise and rebuild its armed forces. A new draft law envisages a doubling of troop strength and a significant increase in military expenditure to counter external threats. These plans would enable Poland to become one of the largest armies in the Europe and to achieve strategic autonomy within the EU and NATO. This InfoFlash will look at what drives this new law. It will also explain what the law entails and how the country plans to finance the new plans. Finally, most importantly, what consequences this future “Great Army” could have for Europe.
