That's an unfortunate reality for the country, and its future. I believe many of them at some point would like to return in the case that the current political and social environment were to get better. It is what it is now.
How fair is that though? I would imagine that a majority of individuals in many countries around the world would like to like in the US, China, Japan, or Europe if they could. Is 73% markedly higher than we would see in India, Iran, Pakistan, or Nigeria?
The last time my country was at war September 1900. We didn't even participate in the World Wars since by the time we made the long exodus to the European front the war was over. So our track record is pretty good, compared to the US who hasn't seen a single decade in its existence without being at war with someone.
However, when I said 'peace' I meant in the interpersonal sense. The US is nice, but there's something to be said about living in a homogenous environment identical to that of your youth.
