I argue that the preservation and expansion of democratic societies and the diminution of autocracies is a vital interest to the US. A free Ukraine strengthens the power of people to rule themselves rather than be ruled by elites without jeopardizing the people of Russia. It does threaten those that wish to give autocracies more of a chance in the modern world.

Not invade with conventional troops vital but publish all the intel around the invasion and send money missiles and veterans.

By recent events, Mr John Mearscheimer joins the list of pundits who were hilariously, massively wrong.

> More importantly he said that the west actually needs Russia against China

But based on this, was also completely out of touch to start with.

> Ukraine is not of vital interested to the West.

Is distinguished professor Mearscheimer perhaps forgetting that Ukraine is of vital interest to the Ukrainians?

> They don't need to "take" Ukraine. They just want it as a buffer zone.

They want it tho, the argument is not that they need it. The argument is that they want it. And the "just want it as a buffer" is completely unsupported and hard to believe.

> Ukraine is not of vital interested to the West.

When they decide they want part of Poland and Estonia too, will you say those countries dont matter for the west too? Will their membership in NATO then matter?
