Why the EU will never have political union

You only have to watch the EU's divided reaction to what is happening in Gaza to understand that there will never be a common foreign policy.

1. The Czechs, the leaders of the official EU diplomatic visit, called Israel's move “defensive”, before rapidly withdrawing the remark.
   
2. The Swedish Foreign Minister, Carl Bildt, a member of the EU mission, criticised Israel unequivocally for choosing to “dramatically escalate” the crisis.
   
3. France, which is about to relinquish the EU presidency, called for a ceasefire
   
4. Gordon Brown called for an immediate ceasefire.
5. The Dutch Prime Minister said Israel could not be condemned as long as Hamas was firing rockets.

And after all this, is there anyone in the EU who still believes in political union?
