Politics & networking internationally: I want to reach out to expat finance professionals. How should I go about this?

With serious talk of trade wars and catastrophic fiscal policies and general unprecedentedly huge uncertainty, we live in interesting times, to put it mildly. I'll be frank: I'm wary. But a lot of people hate talking "politics".

I'm one of those guys, regrettably, seriously considering leaving the USA before something terrible happens here. Yes, I know Buffett is still bullish on the USA. I'm worried if he's wrong (for once) and fearful WSJ & NYT op-eds are right.

So:

Reaching out to alums in London or Hong Kong or wherever else, should I be generic or transparent?

What should I send in the initial email? What should I reserve for later?

What questions should I ask?

It feels like I'm walking on eggshells. Am I?
