UPDATE: Looks like OP's wish has been granted. Around 40 nations have agreed to help crush ISIS before they do anymore damage. I'm yet to read a newspaper which lists all of these 40, however so far I can confirm these nations are particpating (alongside the US): Egypt, Iraq, Jordan, Lebanon, Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, United Arab Emirates, Turkey (only humanitarian support through NATO bases on its soil), Canada, Netherlands, Germany, France, Britain and Australia. No country is sending troops in, though.
