What a lightweight video. They simply claimed they're a defensive organisation and provided no evidence to back up the statement. In fact they deliberately neglected to even try to justify how they got involved in all kinds of conflicts that didn't involve their own members. And as for "every sovereign nation has the right to choose its own security arrangements" - what does one say to that type of brazen hypocrisy? It's like me beating up someone for their lunch money and going around asking people to sign my anti-bullying petition.
You're more likely to encounter the opposite situation in the real world, this video looks like a propaganda piece, it's a bit too overproduced with the sappy background music and the poor Ukrainian dude with his victim face.
"Senator Rand Paul and former Hawaii Representative Tulsi Gabbard have been listed by Ukraine among a number of American politicians, academics and activists Kyiv claims have promoted Russian propaganda."
