Lets keep thing simple : NATO ensures support from other members if your sovereignty is attacked. Meaning you don't need to only depend on your own Military capabilities in order to protect your borders. Finland joining makes Finland's borders a FAR more expensive attack than was previously. > joining NATO only makes NATO less secure as a whole NATO is not an offensive/invading force. It's a defensive force. If NATO had what you're referring to as a level of security, it has only increased due to more forces available to respond. It's that simple.
