One thing this thread isn’t really considering is the ability to leave. Americans can all, in theory, move from Texas to another state without difficulty. In practice, leaving one’s family and support network is difficult enough that most people don’t. Moving countries is exponentially harder, and even in a war, not everyone can leave.
Another factor that complicates Gaza is that Gaza isn’t really a country. It’s more like a giant reservation. Yes, there is local government, but given the history, what resources the Strip has, the neighbouring countries, and various other factors, it’s debatable how much can really be changed.
I left the US and have no regrets. I don’t feel like I owed anything to the country or its people; it’s where I was born and raised, and I’m definitely culturally American, but it’s also very clear to me that some of the problems (e.g. guns and healthcare) are simply intractable. I could devote my life to moving that needle very slightly, or I could leave. While I admire the people working for positive change, I figure that I’m leaving for the same reasons my ancestors came to the US in the first place: a better life.
The thing is, once you leave for a while, the country you’re from ceases to exist. Events happen, culture changes, and if you’re not keeping up with it, the place you’re from isn’t just geographically distant, it’s also in the past. I never lived in Trump’s America. I read the news, but I don’t really get how America has changed.
It’s also true that you can change a lot from outside the country. You can send money back. You can use your position as a Palestinian / Ukrainian / whatever abroad to advocate for change, to be a visible reminder of these places in the corridors of power. How many ex-pats have made more of a difference by leaving than they would have if they’d stayed? I think quite a lot.
On the other hand, as soon as you leave, you start becoming something else, and your children and grandchildren are at best bicultural, but usually only notionally whatever you started as. By leaving, you also ultimately erase yourself, unless you’re leaving in the thousands and settling together—and even then, you still have to make an effort.
As for me, I continue to vote, though that does very little practical good (not a swing state or district).
