Greece-Turkey tensions and Russia's UN Security Council member status seen as possible difficulties in reaching agreement
NATO and the European Union will formally declare a cooperation pact at the alliance's Warsaw summit in July, officials say, overcoming decades of confusion and mistrust over how to provide security beyond Europe's borders.
Forced together by fears of a Russian cyber attack, a migration crisis and failing states in Europe's neighbourhood, officials say the challenges requires both a military response and a softer security approach, combating propaganda and providing training to stabilise governments.
"If there was a Russian cyber attack, we would not want to spend two weeks in meetings discussing what each of us should do," said an E.U. defence official cooperating closely with NATO.
