Remember Fall of the Shah 1979
I was working in Saudi Arabia when the sh*t hit the fan in Iran in '79. I witnessed many American and UK expats lose all their worldly goods in their desperate escape, some taking only what they stood in. After that, I divested significant possessions and lived out of one hand carried bag.
The Gulf area is unstable, and there are many tensions more akin to what is happening in Tunisia - i.e. nothing to do with Israel, but due to repressive autocratic Western-friendly regimes. The Gulf cannot function without low-cost labour from South Asia - many of whom live in squalor among the gaudy towers of Dubai.
Be careful, be prudent. It is just a matter of time before unpredictable unrest will return.
