From a Reuters article about the EU’s immigration crisis:

The president of Latvia has urged Greece to demonstrate a “changed attitude” on border security to stem a flow of migrants, but sees no need to re-erect Europe’s internal frontiers in response to the refugee crisis or Paris attacks.

“’This is the reason why we really need a changed attitude of Greece and others on border security. They need stronger control and checks of documents on their border because they are the first country that asylum seekers are reaching,’ Vejonis said.

Take a look at this map of Greece. With hundreds of miles of shoreline as a border, just imagine what kind of state Greece would have to be in order to exert ‘control’ over it… Only Donald Trump could think it possible.
