Hezbollah’s mad gamble in Qusair

"There are reports that Hezbollah has taken significant losses. If so, the Shiite community will accept this for a time, but unless Hezbollah can achieve its objectives relatively quickly, discontent will rise if the war in Syria turns into a grinding campaign that provokes many more Lebanese casualties."

I wonder if this will provoke demands within Hezbollah for a change in the leadership.
