You are right about Turkey, but Turkey wasn't that way when it entered NATO. Turkey became the aggressive entity it is now only recently, under its current leader. Many other NATO members are seriously concerned about Turkey. Trump admires authoritative leaders, so he's been sittling between supportive silent to actually encouraging toward President Erdogan. I expect our new President Biden to be substantially less supportive of Erdogan. We'll see. But that doesn't negate the value of NATO or of being a member of that organization.
