Her retirement was announced by her boss Secretary of State Antony Blinken on Tuesday. But the question is why now when the administration is attempting to stay the course and present a strong continued stance on Ukraine, also as Biden is still seeking to get tens of billions in defense aid through Republicans in the House.

While there have been rumors that maybe she could be in poor or declining health, McGovern has told Russia's Sputnik that the notoriously hawkish Nuland was a liability at a moment NATO and Russia are inching closer to direct nuclear-armed confrontation. 

"My best guess here is that the CIA and the Defense Department and the NSA got this message around saying, 'look, Victoria's got her own agenda here,'" said McGovern.

The former CIA official continued to speculate: "'The president doesn't really want to strike these ammo depots in Russia or knock down the [Crimean] Bridge. So we got to rein her in, I guess it's time for her to go to early retirement.'"

Another theory, though not necessarily contradictory to the above, has been advanced by professor of national security at Bowie State University Dr. Matthew Crosston.

He laid out what "a staunch anti-Putinist Nuland was and how fervently she wanted to continue to utilize Ukraine as a platform in which to continue to weaken and/or slight Russia on the global stage — and perhaps even up the ante in that conflict with her support of sending ballistic missiles into Ukraine." But she also knows the Ukrainian side is losing.

She may have seen the writing on the wall as Ukraine forces are in retreat, and wanted to bail before potential total defeat:

"She undoubtedly understood that if American support lessons or wanes, Ukraine loses, period," Crosston pointed out. "Perhaps she did not want to be in the Administration that would be responsible for that outcome."
