What is the main focus of the European leaders' meeting regarding defense?

The most critical focus of the European leaders' meeting is the urgent need for all nations to increase their defense spending. According to the defense policy advisor, Russia poses a threat not only to Ukraine but to all European nations, making collective security investment essential.
