Six percent....wow, that would be mana from heaven. We get 1.1% nominal, and about 0.75% in real terms once the Government has finished taking back with the other hand.
As to the threats; deal with terrorism, but get real and prepare for China. The Muslim Hordes are a long way from assembling their excreta to the point of being a direct threat to Europe, but the Chinese are not.
There are 1.3 billion of them. Their population is growing by almost 50 million a year. The one-child policy has resulted in a situation where the surplus male population is now approaching 100 million.
They are a nuclear power and are entering the space race. They are technically advanced and becoming more so. They are organised, intelligent, hard working, and aggressively expansionist. They will not stop at trade. They will seek land and resources outside their own borders; food, fresh water, women, territory.
They have plans to build a fleet of aircraft carriers and are expanding their submarine capability. This is not doomsaying or fantasy or hysteria; it is happening.
India will provide a limited bulwark against China, but only within her capabilities, and only as far as suits her.
American military power is great, but not unlimited. Already it is spread thinly, and stretched in places. Taking on North Korea or Syria as well as current commitments will leave very little surplus capacity in Uncle Sam's ability to look after Britain or Europe.
If I were of a mind to apply timeframes to things, I might suggest that China will be a military threat to the sovereignty of Asian nations within 15 - 20 years, South Pacific and South-East Asian nations within 20 - 25 years, and Continental Europe within 25 - 30 years.
Enjoy the sunshine for now if you must, but don't be so naive and foolish as to believe that it will last.
