Greek Defense Minister Panos Kammenos warns Europe that if no bailout of its economic crisis is forthcoming, his nation will flood Europe with migrants and jihadists, providing them with papers to travel legally throughout the continent.
Greece is expected to go broke this month.

Kammenos said: "If Europe leaves us in the crisis, we will flood it with migrants, and it will be even worse for Berlin if in that wave of millions of economic migrants there will be some jihadists of the Islamic State, too."
European Union finance chiefs are currently debating whether to continue a bailout plan, with Germany a deciding vote.
"If they strike us, we will strike them," the official said. "We will give to migrants from everywhere the documents they need to travel in the Schengen area, so that the human wave could go straight to Berlin." The Schengen area is passport-free.
Only Britain would be spared the threat, if carried out, as it has retained its border controls.
