The recent spate of terror attacks on mainland Europe has forced many within the European Union to call for the establisment of a common army to detect and defuse external threats. While the topic remains controversial, a fresh call for such a force emerged on the sidelines of German chancellor Angela Merkel meeting with Prime Minister’s of Poland, Hungary, the Czech Republic and Slovakia recently.While Merkel cited better communication within the European Union as an urgent need in the wake of Britains exit, there are many who are seeing this as a sign towards establishing a common army. Hungary’s right-wing Prime Minister Viktor Orban is one of them. "We should list the issue of security as a priority, and we should start setting up a common European army," Orban was recently quoted as saying in a report published in The Independent. Another vocal advocate is Czech PM Bohuslav Sobotka . "We should begin a discussion about creating a common European army," he was quoted as saying by Local.de.In terms of personnels, none of the countries mentioned above figure prominently in list of world's largest army. Germany has the largest force among these countries - at 186,450. France, with 222,200 personnels, is slightly ahead but countries like China (2,333,000), United States (1,492,200) and India (1,325,000) dwarf these numbers drastically. Even North Korea (1,190,000) and Pakistan (643,800) have a far greater count in terms of army personnel than major countries of EU. Therefore, many feel a combined force can be a major deterrence against any threat - terror or otherwise.Currently, EU nations deliberate on various military matters. A mutual defense clause was also added to the Lisbon treaty, calling member nations to come to the aid of other member states. On the ground though, it remains a fact that EU has no military capability and it is the European governments which are in control of EU defense policy, and not EU itself.
