The fact that over 40 nations have join our cause is a clear indication that We are not the only one that think SH and his WMD must go.***
A country is the people, not just the government. And many times governments don't represent people. So when you say 'nations', it doesn't really mean 'nations', but 'dependent governments' that haven't many opcions since they're economic, politic, etc. threatened by your country. And don't forget that the majority of the people of those '40 nations that have joined your cause' actually haven't joined.
