Last week, Hezbollah's Hassan Nasrallah confirmed his group's involvement in Syria. In doing so, he contorted Hezbollah's traditional talk of resistance against Israel -- which has broad appeal in the Arab street -- into a narrow defense of Shia interests. In doing so, he damaged the group's credibility and contributed to growing sectarianism across the Middle East.
With Bashar al-Assad's regime on the brink of collapse, Hezbollah stands to lose a close ally. And by supporting Damascus' repression, the organization has compromised its reputation in a region gripped by anti-autocratic fervor. Given that, an off-balance Hezbollah may well shift gears, focusing less on its regional ambitions and more on domestic Lebanese politics.
