Honestly, I don't think we're ever going to get down to the truth here. All I'm seeing here - and all I saw before this even happened - is two sides set on what's basically a propaganda confrontation. There's no question the activists weren't terribly interested in practical concerns (what they're bringing in was puny and materially near-irrelevant, delivered in an extremely inefficient way) as much as they wanted to make a political statement - and honestly, I think they were probably looking for a confrontation to end as badly as possible in order to make Israel look bad. On the other hand Israel made it a point to stop them no matter what and no matter where, because it cannot afford to show that it is not in absolute strategic control. It would be far from beneath them to take to force and to disregard international law - they've done the latter so much that it's become almost THE official stance for them (i.e. their security priorities override any international law, often blatantly and without shame).
So these two particular rams ran straight at each other for a nice confrontational headbutt. The ram with the harder skull and bigger horns "won" in a total non-surprise. The global village is crying wolf for the smaller sheep.
Honestly, I'm totally unsympathetic to both sides of the incident. I will not be buying the inevitable volumes of propaganda that they will both be churning out in the coming months and weeks. They've both shown that respect for international law, security and peace were the last things they actually wanted in this, and they both deserve to be booed off their soapboxes.
