Hell yeah I would if the same situation happens in my own country.
Typically, you should be protecting yourself, then people you are close with, before you start protecting strangers. Also even if democrats are elected, there’s nothing stopping people from protesting about US supporting Israel anyways. Now do you see a flaw in your logic?
yup tax on empty units in general would help a lot including rent prices, if you want to not pay the extra tax, better lower your rent to a point people can afford. So the tax needs to be high enough for this decision to be made.
