"Blame America" still thrives on American campuses------Why Did Russia Invade Ukraine?

Why Did Russia Invade Ukraine?

...The Soviet invasion of the Americas was not done to protect the hemisphere from harm.

The Sandinistas in Nicaragua were full Soviet and Cuban proxies seeking the overthrow of a number of sovereign nations in Central and South America, including El Salvador, Honduras, Costa Rica and Colombia.

The Soviet campaign of terror then was launched precisely to change governments so that various countries would become Soviet allies.
The government of Ukraine posed no military threat to Moscow.

The "threat" from Ukraine is that its democratic character might "infect" the Russian people.
Putin invades Ukraine. On cue, Walt blames America.

Harvard professor Stephen M. Walt, in "What Putin Learned From Reagan," complains that the United States has only itself to blame for President Vladimir Putin's aggression against Ukraine. 

The professor notes, "Russia's power play for Ukraine takes a page out of the Gipper's playbook," and that Putin's "conduct is not that different from the actions of venerated leaders like Ronald Reagan."

Walt's thesis is that America's support during the Reagan administration for the democratic resistance in Nicaragua, popularly known as "the contras," although unwarranted, was emblematic of what "big powers" such as America do.
