Gaza hasn't been an Israeli colonization target since 2004 when they evicted every Jewish settler from the territory and re-established the 1967 borders in the name of peace.
You can't run a de facto siege against the territory, a total isolation of it, and claim you're being peaceful. That's an act of war. The Gaza territory simply doesn't have a military to fight that war.
So import and export blockades, does not make a hands-off independent state.
Since the pullout there have been a series of conflicts and ceasefire between Hamas in Gaza and Israel. So over that time they have been at peace and at war.
