US has engaged in staging regime changes and military interventions all over the globe, all in the name of its national and security interests. Why can't other countries do the same?

"...US have NEVER done anything as bad as seeking to invade to conquer ..."
Uh-huh. They didn't do anything bad. Only killed a few hundred thousand civilians. Displaced millions. Exploited natural resources of countries it occupied. Made mega-profits as a direct result of all the conflicts they started/provoked/escalated. Committed a wide variety of war crimes. Kidnapped, imprisoned and tortured the innocent.
Yep, none of this is bad. Because they did not "grab lands". Jeebez tangs, you're such a child )))

Oh wait. What's this? US funds grabbing Ukrainian land on the cheap???
