When I was visiting Greece in 80s there were a few cases of Israelis trying to still artifacts and icons from Greek Orthodox Churches. It is a great shame on the nation and the state of Israel. It also puts unnessary negative light on the Jewish people. Shame on thieves and they should be named and shamed in National and International media. It is is also an issue of education and self respect.
