A leading authority in the field of international relations, he has authored several seminal books and lectured extensively around the globe (see his website here).

Prof. Mearsheimer came to wider public consciousness through his 2015 lecture in which he discussed the origin and causes of the brewing Russo-Ukrainian conflict. The presentation is a true tour de force and has posted more than 22 million views to date. In that lecture Prof. Mearsheimer not only offered a superb analysis of the situation, but he also made a prediction that is being fulfilled right before our eyes. This is what he said more than six years ago:

"The West is leading Ukraine down the primrose path, and the end result is that Ukraine is going to be wrecked."

You can watch this now famous 2015 lecture here.

On February 15, 2022 – just nine days before Russia's invasion of Ukraine – Professor Mearsheimer gave a Zoom talk about the intensifying crisis to students at King's College in Cambridge. In less than 25 minutes, he provided a superb assessment of the fragile situation that barely a week later erupted into open war. If you wish to truly understand why this conflict arose and who is responsible, this is the best short explanation you can find. The clarity of Prof. Mearsheimer's presentation is second to none.
