return to live in the killing fields as they have their own country where they can defend themselves against enemies without having to be at the mercy of others

Whoever tells you about "existing anti-Semitism" in Ukraine, it is just rubbish. Half-Ukrainian myself (another half - Russian) I lived in Ukraine in the 60-ies, just an 8 y.o. kid. My school teacher and family doctor were both Jewish; very nice ladies. Never heard a bad word about them. Currently, Ukrainian Prime-Minister is Jewish: V.Groysman. Ukraine is long past any ethnic conflicts. The ongoing war in Eastern Ukraine is not "Ukrainians against Russians"; it is just an on-going collapse of the former Russian Empire and its former re-incarnation as the USSR. 40% of the Ukrainian army soldiers and officers are of Russian ethnic origin. Cooperation between Israel and Ukraine can bring huge future dividends to both countries.

Fortunately, his parents and two eldest brothers emigrated to Haifa in 1936.
His other seven siblings and all their families were murdered by the Germans and their collaborators.

She ,her brother and parents were the only entire Jewish family cell to survive in Lviv. They were hidden separately. My mother in law, then 9 years old could watch through a window how the ukrainiens together with the Nazis killed the jews

The Ukrainians enthusiastically led and perpetrated the mass murders. Much more than German soldiers. Not to forget history, not to whitewash Ukraine. Read the facts, at least give the date of the first big brutal pogroms. See https://en.wikipedia.org/wiki/Lviv_pogroms_(1941)
Read Agnon and others on destruction and loss. And ignore farfetched relic, an NM artist finding key to synagogue .
We support the current Ukrainian democracy over the Russian dictatorship. But not to distort history or kid ourselves about such artificial memorials...

Thank you.
