The flotilla raid happened because Israel (and to some extent Egypt) are controlling what enters Gaza to try to prevent weapons from being smuggled into Gaza. The explicit purpose of the flotilla was to break the blockade. More than one ship was raided. The only one where people were killed was the one where the people fought. Quoting from the wikipedia article you cited:

"The five other ships in the flotilla employed passive resistance, which was suppressed without major incident."

However, I think it's not quite true to say that groups are stopped when they want to help the people in the Palestinian territories:

"Palestinians in the West Bank and Gaza Strip receive one of the highest levels of aid in the world."

It's several billion dollars worth of aid each year. Most of this aid comes from Europe.


If you think a lot of things will change, then it should be easy for you to give two or three specific examples of things that will change.
