Netanyahu adviser 'bullish' on US-Israeli relations after Boston

“I'm pretty bullish about the prospects for strengthening cooperation with the United States,” Dermer continued. “The bulk of the American people stand firmly with Israel. I think they identify with Israel.”

The U.S.-born Dermer has been rumored as a possible ambassador to Washington and is considered a key figure behind Netanyahu's perceived support for Mitt Romney during last year's presidential election. The remarks are reminiscent of Netanyahu's own controversial remarks after the Sept. 11, 2001 attacks, when he called the attack “very good” for U.S.-Israeli relations, before backtracking.

“Well, not very good,” Netanyahu told The New York Times at the time, “but it will generate immediate sympathy.”
