The Israelis appear to have learned from the Bush-Cheney administration.
On Monday morning, NPR ran an interview with Michael Oren, an American-Israeli best-selling military historian and Israeli reservist who is a spokesperson for the Israeli military. (He has also been a contributing editor for The New Republic.) Asked if the goal of the current Israeli operation in Gaza is regime change--that is, the expulsion of Hamas from power--he replied that Israelis "do not want to see continuation of Hamas rule in Gaza," but added, "It is not Israel's explicit goal to topple the Hamas government....That is not the stated goal of this operation. If it happens...there will be many people happy about it...The stated goal is to restore security to the southern part of Israel."
This line echoes the rhetoric used by Bush-Cheney officials in 2002 and 2003. They repeatedly noted that the United States officially favored regime change in Iraq but that the invasion to come was about WMDs and security. If it took regime change to neutralize that supposed dire WMD threat posed by Saddam Hussein, so be it.
