The spin's already begun; they weren't innocent, they were Hamas supporters with links to global terror, lying in wait to ambush and lynch IDF soldiers! You'd think a lynch mob would have better weapons than steel rods and a couple of knives, no? Yet until I hear different, the boat was attacked in international waters and should not have been boarded, end of.
Nothing'll come of it, though, the US has already intervened to avoid condemnation. A few protests here and there, and then it'll go back to normal, and there's only so much people can do - here, a couple of British government ministers have called for an end to the Gaza blockade, but unless the whole of Europe and/or America suddenly says, with a single voice, that military aid (at least!) will be cut off to Israel unless they change, nothing will. Still, no doubt our local Lib Dems will be buzzing at the next meeting - given what the Turkish PM was saying earlier, you won't need to do much, heh.
