His position on NATO is incoherent, leave it one day, stay another.
About the only consistent thing is he wants them to pay more.
..."take their $#@!" being a common theme of his foreign policy in general.
The plain truth is he knows nothing about foreign policy and cares even less.
He thought Belgium was a city for $#@!'s sake.
He's just making $#@! up as he goes along, to please the political needs of the moment.
He's actually for the most expensive and asinine form of amnesty possible, as demonstrated in the videos above.
He's for a 45% tariff. Call it what you will, it's terrible and unlibertarian policy.
