"By Prime Minister Netanyahu's point of view, this is an act of war," Klein said of Lebanese troops opening fire near the border fence between Israel and Lebanon, killing a senior Israeli officer. Klein said it was one of several attacks that happened within 48 hours of his bipartisan congressional delegation visit.
He said he's written a letter to Secretary of State Hillary Clinton, asking for an investigation into whether Lebanon used any U.S.-supplied weapons in the attack.
He also met with American troops in Afghanistan and said he told members of the Afghanistan Parliment that the U.S. involvement isn't open-ended.
"You need to build your military, you need to build up your police," he said he told them. "You need to convince your people that they have a better life under their goverment than the Taliban, threatening people and cutting off their heads. But there's a window here, the American people have tremendous good will, but they expect the Afghanistan people to stand up for themselves. This is not an open-ended engagement here."
