Israel shouldn’t have apologized, they were in fact terrorists all along.
Turkish Police Raid Charity Behind Gaza Flotilla Due to Suspected al-Qaeda Links
Was Israel right all along?

Today, as part of simultaneous operations against al-Qaeda in six Turkish provinces, the country’s anti-terror police raided the offices of the IHH, the Islamic charity behind the 2010 Gaza flotilla. In addition to detaining one employee, the police seized all of the organization’s computers.
The incident is one of several in recent months that would appear to vindicate Israel’s stance that the Turkish-run flotilla was not the purely peaceful convoy it was made out to be. Two weeks ago, Turkish security forces stopped an IHH truck that was supposed to be carrying humanitarian aid to Syria, but was in fact filled with weapons. (The drivers claimed they were working for the IHH; the organization claimed they were not.)
