Hezbollah movement faces hard choices

Hezbollah's ambitions are spreading far beyond its Lebanon home as the militant Shiite movement appears increasingly bent on taking on Sunni foes across the Middle East. It has sent thousands of its fighters into Syria and senior military advisers to Iraq, helped Shiite rebels rise to power in Yemen and threatened Bahrain over its abuse of the Shiite majority.

But the regional aspirations also are taking a heavy toll and threatening to undermine Hezbollah's support at home. The group has suffered significant casualties, there is talk of becoming overstretched, and judging by the events of recent days, even a vague sense that the appetite for fighting the Israelis is waning.

In the recent confrontation, Israel struck first, purportedly destroying a Hezbollah unit near the front line of the Israeli-occupied Golan Heights.
