Top Russian military expert Michael Kofman says it’s a mistake to “waste time” on the MiG debate, arguing there are other supplies and weapons systems that would be more helpful to Ukraine.

“Frankly, a lot of the aircraft Ukraine has put up has gotten shot down,” Kofman said.

“And pushing MiG-29s — are they really going to fly from air bases that are being readily barraged on a daily and nightly basis?”

Zoom out: There’s also the matter of whether Poland itself is willing to risk provoking Russia, though the calculus in Warsaw could change if it received rock-solid security guarantees from the U.S.

Calling a Wall Street Journal report about the potential MiG-F16 deal “FAKE NEWS” on Sunday, the office of the Polish prime minister tweeted: “Poland won’t send its fighter jets to Ukraine as well as allow to use its airports. We significantly help in many other areas.”
