Russia slow to win Ukraine’s airspace, limiting war gains

“There are two basic ways you can describe the slowness of the Russian advance in Ukraine,” said Loren Thompson, a defense analyst at the Lexington Institute, a Washington think tank. “One explanation is deliberate restraint. The other explanation is poor execution. We don’t know enough to identify which is the more plausible explanation, but it’s important to recognize the Russians have all sorts of options they have not yet brought to bear,” including heavier use of cyberattacks against the Ukrainian command and control system and air defenses.

In its latest assessment, the Institute for the Study of War said Moscow has likely recognized that its initial approach failed and is moving additional combat power toward Ukraine.

“The tide of the war could change rapidly in Russia’s favor if the Russian military has correctly identified its failings and addresses them promptly, given the overwhelming advantage in net combat power that Moscow enjoys,” it said.

It's exactly what I was saying yesterday:

“One explanation is deliberate restraint."

"IF"

"If

 it's slow going?

It's because they (Russians) want it to be."

"Both Kharkiv and Kyiv, the capital, remained in Ukrainian hands as Russia faced more resistance than it was expecting, according to the Pentagon."

"I do not buy it. Not one bit."

And before we move on to other things today:

Russia pummels Ukraine’s No. 2 city as convoy nears Kyiv

"Unbowed by Western condemnation, Russian officials upped their threats of escalation, days after raising the specter of nuclear war. A top Kremlin official warned that the West’s “economic war” against Russia could turn into a “real one.”

 I'm afraid, we're already there.
