How will security for up to 2,000 UN weapons inspectors be provided in the middle of a war zone in Syria? Updated 09/18

Syria is estimated to have around 1,000 tons of chemical weapons scattered at various sites around the country.

It will take up to 2,000 inspectors to investigate and remove the chemical weapons from the various sites.

The UN weapons inspectors have already been fired upon when they went to investigate the site of the atttack on 21st August.

ALL of the insurgents, moderates and Islamic Extremists alike, are vehemently opposed to the American/Russian deal to dismantle Syria's chemical weapon because it limits the scope for direct American military action in Syria.
The insurgents will be aiming to scupper the deal in any way they can.
The UN weapons inspectors are therefore at higher risk than even operating in a  normal war zone.
They are highly likely to be specifically targeted for attack by at least some elements within the insurgents in order to stop the inspections..

What happens when some of the UN weapons inspectors get murdered?
Will this provide the excuse to renew calls for direct American military attacks and increased intervention that have been put on hold with the Russia brokered deal?

Will the UN even be able to get 2,000 expert weapon inspector volunteers for this extremely high risk venture?
UN weapons inspectors do not usually go about their business in active war zones. This one has ill defined boundaries between the opposing sides.

How will the UN inspectors be able to do their job in areas that are completely or mostly controlled by the insurgents that are out to stop the inspections?

How will security for the UN weapons inspectors be provided?

How many troops will be required to provide security for 2,000 UN weapons inspectors?

The Syrian army are unlikely to be able to provide the sort of security required.
They are hard pushed fighting a war against the very people that will be out to murder the UN weapons inspectors.
They will not be able to provide security for areas that are within, or very near to, insurgent controlled areas.

Will the security of the weapons inspectors provide an excuse to put foreign troops on the ground (presumably under a UN banner)?

What will be the nationality of these (UN sic)  troops?

Will any of them be Americans?

Will these troops provide the cover to supply even more weapons to the insurgents by America, Saudi Arabia and Qatar?

Will the insurgents try and steal a large quantity of chemical weapons, the location of which has just been pointed out to them by the UN weapons inspectors?

So many questions on the practicalities of dismantling Syria's chemical weapons and so few answers so far.

Another assessment by the LA Times, specifically mentioning that some of the chemical weapons are in the insurgent dominated North of the country.
Syria's chemical stockpile easy to find, hard to get to

Update 09/18

Unnamed 'Pentagon sources' are now being quoted as saying that up to 75,000 armed troops will be required to provide the security for the UN weapons inspectors.
Who the heck is going to supply this many troops?
Is this intended as another excuse to put American boots on the ground in Syria?
