The United States answered a question about the prospect of applying Article 5 of the NATO Charter.

The Pentagon will not talk about the applicability of Article 5 of NATO’s charter in the context of allegations of a missile crash in Poland until the facts are known, Defense Department spokesman Patrick Ryder said.

“I will not speculate about potential “ifs” and “whens”, I will be guided by the facts. Get the facts and build on them,” Ryder said at the briefing.

So he answered the question of what the policy of the United States and NATO implies in the context of such incidents.
