That’s actually an entertaining picture. Imagine all these countries from US, Russia, Norway and Germany to North Korea, Japan, Iran, India and Syria, etc. all sitting around a table, all in concert, with the same goal and executing a perfect plan at nearly the same time and keeping it secret from people and do so successfully.
But to be honest, when you see what some people believe and how gullible some can be, you won’t get surprised if someone actually claims that these happened and a significant number of people believe it. It’s scary.
There is nothing, NOTHING, humanity agrees on. No way in hell would you get 200 odd governments to 'conspire' against you.
