Prime Minister David Cameron has said the £1.1 billion military investment announced today will deal with global terrorism and cyber criminals rather than old-fashioned notions of border defence.
Writing in The Daily Telegraph, he said:
Today's investment demonstrates our approach to national security. There are those who believe we would be safer if we fundamentally retreated from the world. They see new warships and military investment and imagine a Government bent on foreign adventurism.
But the plain fact is that in the 21st century, you cannot defend the realm from the white cliffs of Dover. Terrorist plots hatched thousands of miles away threaten to cause harm on our streets. When fragile and lawless states fracture, migration flows can affect us right here.
