i agree with omegabsw - they knew the risks, let them or their companies charter flights to get them out - they're foreign nationals taking money out of a corrupt and oppressive regime - the upside is the huge pay, the reason is its dangerous - dont take the money if you cant handle it, and dont bitch about it when it all goes pete tong 
I agree totally and not really into politics, most of these guys are the equivalent to commercial mercenaries and should accept the risk that goes with the pay / job.
Declare your income and pay UK taxes etc to be part of the norm, anything else just reinforces the mercenary attitude and should be treated as such, imho....take your money, take your chance....seemples...

I agree with all these comments.

You take the money and accept the risks

Some of the comments on here would be funny were they not tragic.
"most of these guys are the equivalent to commercial mercenaries"
Huh? How many are working for UK companies to further UK interests? How many are on short-term contracts and thus still subject to UK taxes? How many are visiting relatives? How many are volunteers?
You don't know the answer to any of these questions, yet still like to portray them all as 'mercenaries'. Besides which, even if they are living as ex-pats, they still enjoy (in my world) the protection of their mother country.
"Take your money, take your chance." A puerile comment to make in the light of the very real personal danger these people are facing.
Sheesh.

There you go again Nick, my opinion that's all, but because you do not agree with it you insult it!

You don't change!
In any job there is always an element of being paid to reflect your responsibilities, and in some specialist areas to reflect the personal dangers you face. This has been the case since certainly capitalism got off the ground, and is accepted by those in such positions.
When in the armed forces, or working on an oil rig, or perhaps being an explosives expert, let alone a someone working on any energy producing facilities in a highly volatile region, that individual most know the dangers will always be present. The couple who sailed around Somali and were kidnapped knew the risk, but still took it. It is all down to personal choice, and in the case of those in Libya, and other volatile regions, they are either paid accordingly, or frankly, they should be! But all these people do take the money and take their chance.

In these cases it is NOT necessarily down to the British Government (who are responsible for spending our money) to organise at tremendous cost rescue missions regardless! It
never has been throughout history, but in these modern times of the nanny state, as many have stated on here, it is "expected" by those who put themselves at great risk that they should be rescued by our armed forces, or hardware i.e. aircraft.
Yes morality must come into it, along with humanity, if a whole national group are in trouble, or an exceptional special case, as has proved the fact now, but for everyone to think the British Government, no more than USA administration for its nationals, should be
automatically bailed out is wrong.
