According to Juncker, now it is time to invest in establishing real military forces to protect Europe.
"We will have to invest a lot to create a real European defense policy. It is not an immediate project, but it is an ambition," he said.
The European Union is unlikely to establish its own army, Russian military and political analyst Vladimir Kozin said.
According to him, the main obstacle to creating an EU army will be the US.
"The recent NATO summits – in May 2012 and in September 2014 – showed that decisions within NATO are made under US control, and those decisions are usually aggressive. Uncle Sam is unlikely to give any freedom to the EU," the analyst underscored.
Kozin believes there are less difficult ways to maintain security in Europe.
"I think Juncker was just overwhelmed with emotions after the recent terrorist attacks. I understand him. But in order to maintain security EU countries should mobilize their security services and law enforcement agencies," he concluded.
