This round of fighting feels different, more dangerous, to some of Israel's museums. At the Tel Aviv Museum of Art, where there's supposed to be a Brueghel-related exhibition, the director has decided to strip the red walls of the valuable paintings. That hasn't happened there since 1991.

Other museums aren't reacting to the recent attacks that way at all. Even the national Israel Museum in Jerusalem isn't moving its prized antiquities. "It's business as usual," its director told reporters.

"We don't get into a panic and take stuff from the glass showcases," the spokeswoman from another museum said.
