For me Russia is a priority as both most dangerous personally, geopolitically and for family reasons (for start, grand-grand-father was murdered as part of Katyń massacre).
Ideally any, and yes, I’m aware that that currently includes the US. Being located there (though very much opposed to said war) it’s a bit difficult for me to boycott, personally.
I’m not aware of anything I buy/use that comes from Israel, so it’s been a moot point.
I do maintain some boycotts that significantly inconvenience me (Amazon being one; I won’t enumerate them all), so I’m not just making excuses for inaction.
