Ensuring the defence of freedom, independence, sovereignty, territorial integrity, and population belongs to the main tasks of each state. Therefore, countries, in response to the current political, security and economic situation, must earmark, within the framework of their national budgets, a proportion of the available resources to ensure their defence. The aim of the article, based on current trends in the defence budgets of the European Union member states, is point out that not only the global economic and financial crisis and the credit and debt crisis in the euro area have a significant negative impact on the amount of resources, which individual European Union member states earmark to ensure their defence.
