After 19 drones hit Poland last night, Poland has officially invoked NATO's article 4. This means, NATO countries will now consult together because one nation feels threatened. Polish PM Donald Tusk calls it "the closest we have been to open conflict since World War Two". While political pressure could mount for a measured response to the provocation, this does NOT automatically mean we are at war with Russia. Mainly because no one was hurt, this is NOT a Pearl Harbor like moment.
