That is not how law works.
The governments of the Ukraine and the US are supposed to do the investigations and report the result to us.
That is stupid.
You can't post obvious propaganda that claims something was "debunked" without supporting a thing.
The facts are clear.
The Ukraine has a democratically elected government before the 2014 US bribed military takeover that murdered over 30k people.
After 2014, the US was illegally stockpiling US missiles and trying to illegally join NATO.
The is proof positive.
There are dozens of other acts of war by the US and the Ukraine as well, that are well known to everyone.
