Well, almost everyone.
"This is a playoff situation in which you need both teams to lose, but at least you don't want one to win โ we'll settle for a tie," said Alon Pinkas, a former Israeli consul general in New York told the New York Times in June 2013. "Let them both bleed, hemorrhage to death: that's the strategic thinking here."
Efraim Inbar, director of the Begin-Sadat Center for Strategic Studies, stressed the same points in August 2016:
"The West should seek the further weakening of Islamic State, but not its destruction... Allowing bad guys to kill bad guys sounds very cynical, but it is useful and even moral to do so if it keeps the bad guys busy and less able to harm the good guys... Moreover, instability and crises sometimes contain portents of positive change... The American administration does not appear capable of recognizing the fact that IS can be a useful tool in undermining Tehran's ambitious plan for domination of the Middle East."Okay, not exactly everyone.
