Romania\u2019s foreign minister on Friday called Article 4 of NATO\u2019s founding treaty<\/a> \u201can instrument that Romania can use\u201d after a drone, which officials said was Russian, crashed into an apartment building<\/a> in the country.<\/p>\n

Article 4, which allows a NATO member to open formal discussions about threats to its security, has come under renewed focus since Russia invaded Ukraine in 2022, especially in the wake of multiple<\/a> incursions<\/a> by Russian drones and jets into NATO countries\u2019 airspace.<\/p>\n

Oana Toiu, Romania\u2019s foreign minister, said in a television interview that the Friday drone crash \u201cfalls into the category of incidents that justify the use of instruments\u201d like Article 4.<\/p>\n

NATO on Friday blamed \u201cRussia\u2019s recklessness\u201d for the drone crash, which comes amid heightened fears that Russia might seek to expand the war beyond Ukraine to target a NATO country \u2014 and that NATO might be forced to respond. Ukraine is not a member of the alliance, but Romania is.<\/p>\n

Here\u2019s what to know about NATO and Article 4.<\/p>\n

What is NATO?<\/p>\n

NATO, the North Atlantic Treaty Organization, is a mutual-defense alliance created after World War II by the United States, Canada and 10 European countries. Its core provision, Article 5<\/a>, requires members to treat an attack on one of them as an attack on all. When NATO was created, Article 5 put Western Europe under U.S. protection as the Soviet Union was cementing its dominance over Central and Eastern Europe.<\/p>\n

Since NATO was founded, 20 more European states have joined: Albania, Bulgaria, Croatia, the Czech Republic, Estonia, Finland, Germany, Greece, Hungary, Latvia, Lithuania, Montenegro, North Macedonia, Poland, Turkey, Romania, Slovakia, Slovenia, Spain and Sweden. There are a total of 32 members<\/a>.<\/p>\n

NATO has invoked Article 5 only once in its history<\/a>, the day after the Sept. 11 attacks on the United States in 2001. That led to NATO\u2019s participation in the U.S.-led war in Afghanistan, where the alliance maintained a presence from 2003 to 2021.<\/p>\n

What is Article 4?<\/p>\n

Article 4 allows a member state to start a formal discussion among the allies about threats to its security. Invoking Article 4 does not commit NATO to military action.<\/p>\n

An invocation of Article 5 is often assumed to have military implications, but the NATO treaty says only that its members will \u201cassist\u201d the party that has been attacked. That can also mean economic or political help.<\/p>\n

Article 4 states that the alliance\u2019s members \u201cwill consult together whenever, in the opinion of any of them, the territorial integrity, political independence or security of any of the parties is threatened.\u201d<\/p>\n

Matthew Whitaker, the U.S. ambassador to NATO, said<\/a> on social media after the Friday drone crash that \u201cwe stand with\u201d Romania and \u201ccondemn this reckless incursion on its territory.\u201d<\/p>\n

Will Romania invoke it?<\/p>\n

The Romanian authorities said on Friday that Article 4 was in their toolbox as they weighed a response to the drone crash, on the roof of a residential compound in the city of Galati, a major river port<\/a>. But they stopped short of saying they would invoke it.<\/p>\n

\u201cObviously, invoking Article 4 is a joint decision,\u201d Ms. Toiu, the foreign minister, said. \u201cIt is part of the discussions regarding the possibilities we have at this moment.\u201d<\/p>\n

Romania\u2019s president, Nicusor Dan, said he had convened the national defense council and would \u201corder proportionate measures in relation to the Russian Federation.\u201d But he did not elaborate.<\/p>\n

\u201cThe unprecedented nature of the event demands a firm, coordinated, and appropriate response,\u201d he wrote on social media<\/a>, adding, \u201cRomania is a NATO member state and will not accept, in any way, the war of aggression waged by Russia against Ukraine to be transferred onto its citizens.\u201d<\/p>\n

Has Article 4 been invoked before?<\/p>\n

Since NATO\u2019s founding in 1949, Article 4 has been invoked nine times, including on Feb. 24, 2022, the day Russia launched its full-scale invasion of Ukraine.<\/p>\n

Poland invoked<\/a> the article in September after NATO fighter jets shot down Russian drones<\/a> that had entered its airspace. Russian drones had crossed into Poland before, but it was the first time they had been shot down over the territory of a NATO country.<\/p>\n

NATO decided<\/a> to step up its defenses after that incident, including by increasing air patrols and mobilizing ground-based interceptor systems \u2014 showing how easily the war in Ukraine could spill across borders.<\/p>\n

Estonia invoked<\/a> Article 4 later that month, after three Russian fighter jets violated its airspace.<\/p>\n

\u201cNATO stands ready to defend every inch of allied territory,\u201d Mark Rutte, the NATO secretary general, said in a statement on Friday after the drone crash in Romania. \u201cWe will continue to enhance our readiness to deter and defend against any threat, including from drones.\u201d<\/p>\n
