Both Yemen and Jordan have indicated that they would
send troops to Iraq
(Washington Post article).

This is a big deal, but seems to be nearly invisible in the news. This is Jordan and Yemen saying that they (i) acknowledge the legitimacy of Iraq's interim government, and that (ii) its security and stability is their interest (and in the interest of the Arab world). They are now unambiguously telling the rest the Arabs as much. So much for the claim of puppetry in Baghdad.
