That’s the hype in a Fox News article centered on Russia’s flying armed drones through NATO member Lithuania’s airspace.

In recent days, drones launched from the Russian-aligned state of Belarus have pierced Lithuanian airspace, drawing alarms from the region’s political and military leaders. One drone traversed approximately 100 kilometers, loitered ominously over Vilnius carrying two kilograms of explosives and ultimately crashed inside a military training zone. Earlier in July, another drone forced the evacuation of high-level officials when it crashed near the Šumskas border crossing.

Lithuania’s Defense Minister, Dovilė Šakalienė, has responded [paraphrased by Fox News].

while stressing that there is no evidence suggesting the latest drone breached intentionally, said “this is an unprecedented and alarming incident,” especially given that the drone flew just one kilometer from the president’s residence.
Describing the behavior as “reckless drone incursions,” she warned they amount to “a direct test of NATO’s resolve.” In response, Lithuania has pledged to review its defensive protocols and urged NATO to bolster its air defenses as a clear message that the alliance stands ready to safeguard every inch of its territory.

And this, from an outside “expert:”

Andrew D’Anieri, associate director of the Atlantic Council’s Eurasia Center, told Fox News Digital that while it isn’t crystal clear whether Putin is openly testing Article 5, his apparent lack of caution about these actions is telling.
“The kind of alarming thing is, we haven’t seen any real response from NATO to any of these,” D’Anieri said.

Here’s the text of Article 5 of the NATO treaty [emphasis added]:

The Parties agree that an armed attack against one or more of them in Europe or North America shall be considered an attack against them all and consequently they agree that, if such an armed attack occurs, each of them, in exercise of the right of individual or collective self-defence recognized by Article 51 of the Charter of the United Nations, will assist the Party or Parties so attacked by taking forthwith, individually and in concert with the other Parties, such action as it deems necessary, including the use of armed force, to restore and maintain the security of the North Atlantic area.
Any such armed attack and all measures taken as a result thereof shall immediately be reported to the Security Council. Such measures shall be terminated when the Security Council has taken the measures necessary to restore and maintain international peace and security.

Bruno Kahl, Germany’s chief spy…cautioned that Russia’s growing employment of hybrid tactics—ranging from sabotage and cyberattacks to disinformation—raises the likelihood that NATO may ultimately feel compelled to invoke Article 5.

For good or ill (I suggest for ill), Lithuania’s and other member nations’ responses meet the letter of that mutual defense requirement and that nothing, of necessity, would change were Article 5 formally invoked.

A mutual, collective defense arrangement is crucial for defending against invasions or other attacks, but such arrangements are practically executable only when what’s included in “collective self-defense” is understood rather than distorted. Beyond this simple thing, only when what’s included is clearly understood can necessary improvements—which Article 5 so desperately needs—be made.

In furtherance of that last, here is Article 3:

In order more effectively to achieve the objectives of this Treaty, the Parties, separately and jointly, by means of continuous and effective self-help and mutual aid, will maintain and develop their individual and collective capacity to resist armed attack.

This Article is dishonored—other member nations betrayed—by nearly a third of the current member nations as those deplorables steadfastly refuse to fund their own defense establishments much less honor their commitments to fund NATO directly to a percentage of their GDPs.

Article 12 organically provides for review of the treaty’s functioning:

After the Treaty has been in force for ten years, or at any time thereafter, the Parties shall, if any of them so requests, consult together for the purpose of reviewing the Treaty, having regard for the factors then affecting peace and security in the North Atlantic area, including the development of universal as well as regional arrangements under the Charter of the United Nations for the maintenance of international peace and security.

If such a review is not carried out in any serious manner (see the shortcomings above), then it’s time for serious nations to leave NATO (as Article 13 provides, or without it) and form a new, actually serious mutual defense arrangement.
