President Donald Trump, who issued what many described as a chilling warning to Russian President Vladimir Putin: “It could be big trouble.”

Silent, Unannounced, and Deliberate

Estonian military officials revealed that the Russian warplanes:

Filed no flight plans.
Shut off their transponders.
Ignored all radio contact.
This kind of maneuver is considered a deliberate show of force. Military analysts explained that flying “dark” in such a manner is not an accident, but rather a calculated tactic to intimidate and test NATO’s response.

“This was no navigational error,” said retired NATO air commander Col. James Whitaker. “When three MiG-31s enter the sovereign airspace of a NATO ally, remain for more than ten minutes, and refuse to communicate, that’s a deliberate violation. The message is clear: Russia wants to remind NATO it can poke at its borders at will.”
