We will stay out of Syria, due to it being in the Russian zone of influence and a base for their Mediterranean fleet. Russia, China and the US always avoid direct conflict to make sure the obvious MAD situation does not occur.
Iran will be where it happens as they will have a viable nuclear device within two years. Neither the US or the Israelis will allow that to happen. If they do then they will attempt to use it, which will result in a pretty much one sided nuclear exchange, by Israel and probably the US, which is bad news for humanity and Iran's population, with many of the younger generation against this oppressive dictatorship (dissidents are ruthlessly destroyed) anyway.
With Syria there is a big problem of where their chemical and biological weapons are stored. They may yet be used by Assad, but if they fall into other hands, who knows? Syria supports Iran and Hezbollah who in turn support Pakistan, Afghanistan and Al Qaeda. While Al Qaeda hate the Syrian's Assad and may well have been behind the recent suicide bombing of senior personnel. So anybodies guess what will happen here?
So will Assad decide to go out with a bang, or will they fall into the wrong hands, a chemical or biological device in London over the next three weeks with the Olympic games would create the sort of headlines terrorist like. I'm sure MI5 and MI6 are very aware of this and many other terrorist threats and are very active in preventing any terrorism at the games.
The UK has a bad habit of running down our armed forces, just before they are need in a big way again.

Although some good news is that we took delivery of our first test F-35B this week. Wehave two more on order and will order another one next year. The good news is that production should ramp up by Lockheed Martin and BAE by 2015 to producing one a day as we may need some quick deliveries.

The current US in service date is 2016.
We are living in dangerous times.

Spain and the Spaniards have a choice, keep living the illusion by clinging onto the vanity project the Euro, where they benefited from cheap money and EU development funds from joining the Euro by building airports they don't use, roads they don't need and houses they can't sell as part of a big construction bubble. They had 10 years of partying and now they have run out of drink and are going through a 10 year plus hangover. The paracetamol is default and exiting the Euro as this will cure what will otherwise be in theory a 10 to 20 year depression (except they can't stay solvent that long) and they will get to keep a democratic system of Government.

The PIIGS will bankrupt Germany if she is stupid enough to let them, now with borrowing approaching €1.3tn, when the PIIGS along with France and possibly Belgium exit the Euro, what happens when Germany asks what will probably be €2tn+ by then back and they say no, will it be decided by normal dispute resolution apparatus or by a more direct method? Who knows?

My suggestion would be we sit back and let Europe sort it out themselves this time, after all we are all still paying that temporary tax to fund the Napoleonic Wars. Income Tax!
