The shock of refugee crisis from the fall of 2015 and terrorism in European
Union space has called again into question the topic of European
borders. In the present paper we intend to show that the process of the
European integration has been marked by the division within the EU
especially after the last enlargement eastward (2004/2007) take forms of
fragmentation. Initally, the financial and economic crisis has produced
new forms of division which have fragmentation aspect designed to create
new European borders in the area of EU, but related to the internal process
harmonization. Secondly, the Ukranian crisis, due the implications
on external security of European Union, will multiply the fragmentation,
but in this case being disputed the national security of the states located
on the eastern borders of the EU. Finally, the refugee crisis has led to a
real psychosis of security not only at the external borders of the European
Union but also to the internal borders reaching national security sensitivities
of member states, hence there is danger that the EU not only to close
between hard borders but to bring the European project decades ago.
