I think Q may have tried to backtrack like he did with the true definition of NWO recently.
If you think Israel is the keystone, some further thought points to the Jews worldwide as the real keystone, because Israel's significance and power depends on them. Q also used the word "Nation" next to one mention of keystone, and Jews are a nation by the technical definition while Israel is merely a nation state. This was discussed on /cbts/ back then.
