For the first 40 years of NATO's existence it sought to undermine democracy and reinforce the states of NATO aligned countries in Europe through terrorism and assassination.

They then rather genocidally carpet bombed Yugoslavia killing and wounding thousands of civilians ( many of whom were from Kosovo the people they purportedly wanted to help), 3 foreign diplomats by bombing a foreign embassy not in anyway involved in a conflict and completely destroying the infrastructure of Serbia.

They then genocidally invaded Afghanistan where they destabilized the country, toppled the government and then put pedophile psychos in charge because they were the ones willing to work with us, killed nearly 100,000 civilians, and then ended up putting the original government back in charge 20 years later.

Finally they genocidally took the most prosperous country in Africa, a country with universal college, healthcare, jobs programs, and housing, a desert country that had a 200 year supply of water and bombed the fuck out of it, destroying the water supply, plundering the gold, supporting the precursors to ISIS, and turned the country into a place with fucking slave auctions.

But yeah NATO isn't genocidal, they just topple governments and bomb/terrorize civilians.
