Stop,
I don't disagree with you at all. We have one million fit healthy young people "not in education, employment or training" (NEET's) here in the UK currently in the welfare trap. Then we have another dreadful African genocide which requires substantially more than a regiment or two to achieve a lasting long term solution.
However, there is no will to join up the dots and do whats neccesary...to many "ism's" to overcome.
Forget the UN, its a complete waste of time, yet there is no appetite at all for painting bits of Africa pink again, even though thats probably the only thing that will save lives in the long term.
But what I wouldn't want to see is yet more of our soldiers lives being lost (or worse, remember what happened to the Belgian peacekeepers in Rwanda?) and another intervention that drags on year after year with people rapidly forgetting why they went there in the first place. It'd be Northern Ireland on massive grotesque scale. You can't just drop in for a month and be home for Christmas, you need to stay there and govern for two or three generations and even then...look at Kenya.
