Military expenditure

Today I heard that the UK government  has agreed to upgrade Warrior military vehicles at a cost of £1 billion. Will these really help quell riots on our streets or make the world a safer place?

Like the decision to upgrade the Trident submarines at costs up to £100 billion over a lifetime, I cannot understand what possesses our politicians. In an age when budgets are tight there are surely better ways to safeguard national security that to throw away money on rubbishy things like this.

Do we NEVER learn that wars rarely achieve anything other than stirring up hatred and bad feeling for years to come? Although not a Quaker myself, I am a firm supporter of the Quaker way of peace and reconciliation.
