Love all these yahoo's trying to spin this as a victory for trump's lunatic policies as if NATO is some kind of social club with members not paying their 'subs'. lol. While America may spend more than most NATO countries they do actually gain a lot strategically. They have their bases, planes and missiles in Europe where they can be deployed much quicker than if they were in the US. In return countries who share common interests with the US benefit from the additional security of having such weapons within their borders. Trump has boiled it all down to some stupid idea (for the benefit of his gormless supporters) that people 'aren't paying their dues' as if it's some 'Godfather' style protection racket! It's all just lame excuses to undermine an organisation that although isn't perfect (lets be honest - what is) helps keep the true 'Mob' organisation that is the Russian federation at bay. It's absolutely obvious trump is compromised in some way to Russia. Whether it comes out in this Mueller report, I don't know, but his actions in Helsinki, his secretive conversations with Putin, his attitudes towards sanctions, his disdain for NATO, his uncomfortable ties to Russians and his lies about all of the above point to someone compromised, dangerously deluded and completely unfit to 'lead' a bunch of boy scouts never mind a country.
