It's a step improvement: It gets you over the border to a comparable place while being close enough to family for now. The risk of "borders are secure now, nobody gets to leave" is non-zero in the US' future. The way political litmus tests are affecting civil rights here is scary as hell too.

On the military angle, I'd much rather live in a country without nukes. But I'm willing to kick the nuclear blackmail risk can down the road, my own government's threats are way more immediate.
