Pauline Kleingeld argues that according to Kant it would be wrong to coerce a state into an international federation, due to the wrongness of paternalism. Although I agree that Kant opposes the waging of war as a means to peace, I disagree with Kleingeld's account of the reasons why he would oppose coercing a state into a federation. Since she does not address the broader question of the permissibility of interstate coercion, she does not properly address the narrower question of (...) whether coercion to compel a state to join a federation can be permissible. I revise and supplement her arguments. (shrink)
