How far will the Syrian regime push western powers?

It was confirmed yesterday that the Syrian regime used dangerous chemical weapons on population centres in Syria. So far two chemical weapons have been fired that's according to U.S. intelligence.

Also British Prime minister David Cameron has said there is growing evidence of the use of chemical weapons by Bashar al Assad's regime, condemning reported attacks as a "war crime".

U.S. commanders have laid out a range of possible options for military involvement in Syria, but they have made it clear that any action would likely be either with NATO backing or with a coalition of nations similar to the NATO-led overthrow of Libyan dictator Col. Moammar Gadhafi in 2011.

But when looking in detail to Syria's defences and weapon systems it becomes clear it's not going to be like Libya where it was just a "in and out" job. Syria has much more advanced missile systems then Libya and has the capability to deploy Anti-Aircraft missiles at any time and fire at nearly any western jet that enters Syrian airspace. The other worry is Syria's tactical ballistic missiles which can inflict significant damage against a enemy force if a attack is successful. These missiles have a range of around nearly 200 miles. 200 miles would easily be in range of many Syrian cities or conflict zones depending where the missile is based.

The other problem is Syria's handheld anti aircraft missile systems named "Strela 2" they have the capability to deploy over 15,000 of these anti aircraft missile guns. 15,000 is very significant indeed and are a danger to any Western forces.

At the moment if Western forces decide to strike on Syrian soil they will have to either jam radars or fire cruise missiles on air defence systems.

The Syrian regime is becoming increasingly desperate and I expect further chemical weapon attacks and the more chemical attacks the more the prospect of foreign intervention.
