That's not what an EEZ is for (despite what the Chinese may think). UNCLOS provides for enforcement of domestic laws in EEZ only with regard to the exploration, exploitation, and conservation of living resources. The legality of the blockade is not really in dispute, but you don't have to make up rights of seizure in EEZ's or sovereign rights (i.e. border control) to a territory Israel asserts it no longer occupies to defend that claim.
What's at stake here is not the legality of the blockade but how far Israel is willing to go to enforce it. It was completely rational to resist - the convoy wanted to see and document how far Israel would escalate. The legality of the blockade doesn't resolve the subjective question of the level of force appropriate to enforce it. Despite the rhetoric about Israelis not caring about public opinion (external or internal), they clearly did not want to kill people to stop a convoy of food, medicine, and construction materials - hence why they went in with non-lethal means. Yet they let themselves get goaded into a very bad position, compounded by their own tactical mishandling of the situation.
So what exactly is your point?
I wasn't arguing the legalities of the use of the EEZ, I'm saying that reasonable mariners (such as bona fide merchantmen) conducting lawful behavior do not respond to boardings the way the "activists" did in a host nation's EEZ. It's a good way to get shot or hurt.
The boarding team properly identified themselves and the capacity they were functioning in. If the USCG intercepts a suspected drug boat, even the drug runners know better than to act that way.
The USN also conducts E-MIO, similar in terms of driving principles to the Israeli blockade, which can actually be conducted in international waters. Do you oppose that as well?
Finally, tactical mishandling is a nice way of armchair quarterbacking. They didn't want to KILL because they had no justification to do so going in. So they went in with non lethal force (appropriate level of force), and escalated in response to a deadly force threat (knives, baseball bats, getting thrown off the vessel, metal pipes). I can't think of any competent military organization that would not have responded with lethal force at that point.
I really don't understand the "outrage" at what Israel did. And I thought Netanyahu's speech today was an excellent plea for sanity, which unfortunately, I doubt they'll get.
