There is oodles of evidence that the CIA have been
operating in the Ukraine from before 2014 until now
and its unrealistic to think that the US would pour hundred's

PS: The CIA / Pentagon are secretive organisations when
it comes to US involvement in wars (NB the convulsions re Wikileaks) and rightfully so;
otherwise why telegram US intentions/operational details to the enemy.

Denial is the refuge of cowards, IMO, but that happens in every war
and the facts are only known generations later once the war is done and
dusted (EG: Vietnam)
