Ultimately, it will probably be impossible to arrive at answers to those questions that will be universally accepted. And in the immediate term, trying to answer them may not matter. The more important problem is that, regardless of the motives of those involved, the results of the incident have left Israel deeply isolated, and that is a much graver threat to its long-term security than whatever those ships were carrying. The ships came from Turkey, Israel's closest friend in the region. That relationship is now in tatters, and more humanitarian vessels are now on the way. Egypt, who joined Israel in calling for the blockade of Gaza, may now feel pressure to drop its support for the sanctions. Already it has opened its border with Gaza and is accepting Palestinian refugees and is allowing humanitarian supplies to flow in. And the civilian deaths have made it difficult for Israel's allies in the rest of the world — including the United States — to come to its aid.
