Washing my hands of AIDS?

As Britain heads towards a budget deficit of £128bn by 2010/11, can it really afford to spend £6bn tackling the AIDS epidemic in sub-saharan Africa?

If £6bn is essential to save so many lives, why not spend £10bn instead!?!

Would more lives be saved by raising basic levels of hygiene by buying essential items like soap rather than jumping on a popstar inspired bandwagon?
