NATO ambassadors will meet on Wednesday at the request of Poland on basis of the alliance's Article 4, two European diplomats told Reuters after an explosion in Poland close to the Ukrainian border reportedly caused by a stray Russian missile.

Be a little bit careful with this: Don't confuse Article 4 with Article 5.

Article 4 creates an urgent conversation between NATO member diplomats on collective security, but has also happened several times in the past. Don't confuse it with Article 5, which is invoking the mutual defense treaty obligation in response to an armed attack.

But still Article 4 is a substantial step, and an indication of how serious #Poland is taking it.

@Pwnallthethings at first I thought you were talking about paper sizes.
@basementbox @Pwnallthethings Me too. And I was starting to compose a rant in my head about the higher numbers being smaller sizes.
"Why the heck is A5 smaller than A4!"
