What NATO foresees in case of an attack on a member country!

Poland, which according to initial reports was hit by a Russian missile with two casualties, can use Article 5 of the NATO treaty, which obliges member countries for collective defense.

What does this rule define?

"The Parties - it is stated in the text of Article 5 - agree that an armed attack against one or more of them in Europe or North America shall be considered an attack against all of them".

But what else does Article 5, which has been invoked only once by the United States after the terrorist attacks of September 11, provide:

"...therefore (the parties) agree that if such an attack occurs, each of them, in the exercise of their right of self-defense, individual or collective, recognized by Article 51 of the Charter of the United Nations, will assist the party or parties attacked by taking immediately, individually and in cooperation with other parties, such actions as it deems necessary, including the use of armed force, to restore and maintain security in the Atlantic region of North.

Any such armed attack and all measures taken as a result thereof shall be immediately notified to the Security Council.

These measures will end when the Security Council has taken the necessary measures to restore and maintain international peace and security."

Article 5 is the pillar of NATO.

Initially, there were 12 NATO members in the alliance, while now there are 30, including Poland.
