Just one note about Article 5 "ironclad commitment" and WWIII.

The article 5 says: "The Parties agree that an armed attack against one or more of them in Europe or North America shall be considered an attack against them all and [...] each of them,[...] will assist the Party or Parties so attacked by taking forthwith, [...] such action as it deems necessary"

It doesn't mean at all that if there is an invasion by unmarked troops coming from Belarus into Poland that Washington is going to send all the nukes on Moscow.

For example, they could consider appropriate reaction to send financial "support" (like a loan), but they don't have to declare or enter total war (which is a common misconception).
