Fun Fact, a NATO response requires all of its members to fight together as one. The Yemen strikes was an operation supported by 8 of its members, not by NATO. In much the same way, US invasion of Iraq was not a NATO response and in fact several NATO members condemned it when Bush attempted to invoke article 5 after the World Trade Center was destroyed, but I still think that would have been a much better citation for you to use.
