Our prayers for those in Boston, our thanks to those in Israel.

Israeli Police Chief Yohanan Danino and his senior staff departed for a scheduled visit to Boston to meet with FBI and other US law enforcement officials. Danino will work to further law enforcement cooperation between the two nations and provide Israeli expertise in the investigation into the marathon bombing.

By contrast, members of the Palestinian organizations Hamas and Islamic Jihad reportedly danced and handed out candies in the streets of Gaza after hearing about the spilling of American blood. Islamists in neighboring Jordan told local media that the Americans deserved such terror.

Chief of emergency services at Massachusetts General Hospital, which treated the bulk of those wounded in the Boston Marathon bombing, credited Israel with preparing his staff to effectively deal with such an scenario. Two years ago Dr. Alasdair Conn invited Israeli experts to train his staff on handling mass casualty situations. That training was put to good use on Monday, and Massachusetts General was widely praised for it handling of the situation.
