It's unclear how many nations will sign up. Some such as trusted allies Britain and France harbor bitter memories of joining the U.S.-led "coalition of the willing" in the 2003 invasion of Iraq that included troops from 38 nations.
I nearly spewed my drink on my screen at that one.
While Britain did indeed commit an entire ground division plus supporting air and naval forces, France's contribution to the 2003 coalition was a sneer and--well, just a sneer.
France sat that war out. Although France almost participated, we weren't quite sure what their game was.
I did not bother to read any more of the story.
