Donald Trump is not yet the Republican nominee for president. But his recent comments encouraging Russia “to do whatever the hell they want” with a NATO member that is not paying enough for its defense was enough to raise the hackles of everyone from European leaders to President Joe Biden.

After all, while NATO certainly needs the United States’ military and political might, the U.S. also has several important reasons to support NATO, writes Klaus W. Larres, a political scientist and expert on US-European relations.

“Trump does not view Putin’s Russia as an existential threat to the U.S.-led global order. And thus he does not seem to realize that the U.S. and its European allies need protection from Putin’s Russia, the kind of protection offered by NATO,” Larres writes.

Larres explains how NATO works and its overall effectiveness at helping maintain peace and security across Europe.
