Americans in Exile (semi-permanent and permanent) [View all]

Would like to start a discussion on this topic.
I have lived for 25 years in Asia. I am American, remain American, involved with American politics, but I have no intention of residing in the US again. My question can exiles still be relevant in our political discussion? Is exile a viable option now under Trump? What can be learned and done during a long period abroad and how does it compare with the experiences of other political exiles from other nations (E.Europe/USSR, South America, Africa, Asia)?
