I don't think it is a particularly good idea either, but in general I'd prefer to see British troops involved in protecting civilians attempting to overthrow a despot than other recent forays into the near east. Wishful thinking obviously.
It now appears that a few thousand home grown demonstrators can change the world of evil dictators than all the resources put up by the US and Britain and met with failure to boot. Lessons learnt should not to interfere in how other countries are run because you disagree with them!
The secret weapon is obviously Facebook and the internet.
The key factor for dictators from Julius Caeser to te present day is staing in control of the Army.
It's difficult to know whether to what extent that is the case in Lybia right now but if the Army is fully behind him - well you can't fight machine gun fire with bottles and bravado
Security for protesters could mean British soldiers fighting the Libyan forces, who have in turn been armed with weapons supplied by Britain. No thanks! Secondary to that, this is, thanks to Ed. and his widget, the first time that I have seen twitter at work and it looks like a madhouse to me.
"Would anyone support western intervention to provide security for protesters?"
If it can be confirmed that Libya is using its air force to bomb/strafe protesters, NATO should destroy Libya's airfields and promise to shoot down any planes it sees in the sky.
