Israel and Lebanon have more pressing concerns than war with each other, but bickering could escalate to incite war if the US and Europe don't help.
Lebanon finally has a new government after five months of political bickering. But Western policymakers should not shift their attention away from this small country that has been the staging ground of proxy wars in the Middle East.
The new US-backed Prime Minister Saad Hariri will share power with the Shiite militant group Hezbollah and its allies. When Mr. Hariri's coalition won parliamentary elections in June, a seductive conventional wisdom emerged in the West: Because Hezbollah and its partners were defeated at the polls, the group would lose some of its luster and a pro-US alliance would rule Lebanon.
In fact, Hezbollah remains the dominant military and political force. It holds the key to both domestic and external stability in Lebanon.
Hariri's government will have no influence over Hezbollah's militia and its weapons buildup along Lebanon's southern border with Israel – the most volatile border in the Middle East today. If there is renewed conflict along the border, it could be a catastrophic setback for stability in the region. The United States and Europe must ensure that does not happen.
