holy shit dude... this is terrible news. Your property in Cambo is destroyed? How? taken over by locals?
I would offer some advice but man oh man, I have none. I think getting out of USA and heading back to Cambodia is the best move but I would imagine you and the wife are likely thinking more along the lines of what is best for the kids.
I'm sorry to hear that things are bad. I expected them to be less-than-awesome but not this bad.
