Syria - what is to be done?

I do not have words to describe my horror but this image will live with me for a long, long time.

The UN has teeth, it just isn't allowed to use them. Any new organisation will have identical problems.

I am beginning to wonder whether the UN is passed its sell by date and something new and different with teeth needs to be set up.

The UN seems very effective at wringing its hands and not much else unfortunately.

If someone knew what to do, it would have been done several years ago, but Syria, like North Korea, is a problem without a a workable solution.

Last paragraph says it all.

Can it get any more vomit inducing and heart breaking, than knowing your own country is cosying up to the Saudis and selling them vast quantities of arms, which are then used to deadly effect in the Yemen......whilst we give humanitarian aid to the Yemen to relieve the suffering caused by those arms.
Please everyone, consider supporting a small but committed and effective charity called CAAT, Campaign against the Arms Trade.

It is like musical chairs, our constant interference in things that can never be ended and we side with people, who then change tack and all we do is make things worse.

Keep our bloody noses out, that is what needs to be done, everywhere.

mcem, the same could be said about our weaponry being used by Saudi Arabia against Yemen.

And we're leaving the trade of the EU to sell arms to the Middle East to blow up Yemen and then we're sending aid to Yemen.

A connection has been made and I'd need reasoned and logical argument/explanation now to dislodge it.
The very simplistic thought is this - It seems that Assad's forces caused this latest tragedy.Theresa M negotiates arms deals with those who support Assad.
How can UK not be indirectly responsible?
