Cameron: Leaving EU Hikes Risk of War

LONDON (AP) -- Raising the stakes in Britain's European Union membership debate, Prime Minister David Cameron said Monday that leaving the bloc would increase the risk of war in Europe.

Cameron's speech on national security came as campaigning ahead of a June 23 vote on the country's EU membership moved into its final weeks.

Cameron said it would be rash to assume that "peace and stability on our continent are assured beyond any shadow of doubt." He said the EU "has helped reconcile countries which were at each other's throats for decades."

"Britain has a fundamental national interest in maintaining common purpose in Europe to avoid future conflict between European countries," he said.

"And that requires British leadership, and for Britain to remain a member."

Cameron argued that "isolationism has never served this country well. Whenever we turn our back on Europe, sooner or later we come to regret it."

Whether leaving the 28-nation union would make Britain more or less secure is a key referendum battleground. Two former U.K. intelligence chiefs said in an interview published Sunday that the EU gives Britain an edge in gathering anti-terror intelligence and underpins continental peace.

Cameron said that, with the fight against the Islamic State group raging and an assertive Russia flexing its muscles, "now is a time for strength in numbers."

The anti-EU campaign group Vote Leave called Cameron's claims "historically illiterate," arguing that NATO contributes far more to European peace and security than the EU.

"The notion that the peace of Europe was guaranteed by the institutions of the European Union was always utter nonsense," said Robert Cowcroft of the University of Edinburgh, a member of Historians for Britain, an anti-EU group.
