In 2012, my sister sent her son to Israel to study, and in the end the child stayed there, loving everything. He holds a high position, praises the country, and now my son is also invited to go there. My ninth finishes, why not? But I don't like Israel itself, what else is there of similar quality?
Any boarding schools in the USA will be no worse than Israel, and the situation there is calmer now. I used to look in that direction too, but after the recent events I changed my mind. In the US you can choose an educational programme purely for America, if your child stays there, or you can go on an international study programme. This is if you plan to look for a university in another country.
