You are talking out of your ass.

"The Lisbon treaty leaves it vague and open to interpretation, NATO's article 5 does not. It's very clear."

Wrong. NATO Article five simply states aid, not military aid. It's up to member states. They know that small nations couldn't possibly contribute as much, maybe not even military.

"With the invocation of Article 5, Allies can provide any form of assistance they deem necessary to respond to a situation. This is an individual obligation on each Ally and each Ally is responsible for determining what it deems necessary in the particular circumstances.

This assistance is taken forward in concert with other Allies. It is not necessarily military and depends on the material resources of each country. It is therefore left to the judgment of each individual member country to determine how it will contribute. Each country will consult with the other members, bearing in mind that the ultimate aim is to “to restore and maintain the security of the North Atlantic area”."

Go read the damn thing before guessing wildly during an international crisis.
