Knocking down the wall, but which wall?

According to Ha'aretz, Afghanistan is considering diplomatic relations with Israel. Israel's foreign minister, Sylvan Shalom used a wonderful turn of phrase to describe Israel's attempts at diplomacy among Arab and Muslim regimes.

The Afghani report coincides with Foreign Minister Silvan Shalom's efforts to knock down the "iron wall" between Israel and Arab and Muslim countries. "Muslim countries understand this is the right time to initiate contact with Israel because anyone who wants to be involved in the peace process must have contact also with Israel and not only with the Palestinians," the Israeli sources said.

Whose wall is it anyway?
