>>50316318>1 lion can fit in a 1 meter by 2 meter rectangular box (2 square meters)>1 square kilometer is 1 million square meters and can thusly fit 500,000 lions>1 billion lions could therefore fit in an area of 2000 square kilometers>the smallest American state has an area of over 3000 square kilometersAll the Psychic-type Pokemon and some assorted others work together and deport all of the lions to Rhode Island, then employ suggestion and American propaganda to make them think they don't want to leave. Since redistricting just ended, the additional 1 billion residents of Rhode Island don't factor into that state's congressional representation for another 10 years at least. In that time, everyone else in Congress knows that, if the lion situation isn't resolved before the next census, every other state's reps will be outnumbered 3:1 by Rhode Island lions. Since lions are from Africa, that would mean that a large part of the US government would be dominated by African-Americans forever. Obviously this can't be allowed to happen, so a bill that makes being a lion outside of a zoo or a circus in the US a crime punishable by death is passed by a vote of 434 to1 in the House and 98 to 2 in the Senate. Red-blooded, gun-toting Americans from the South and Southwestern states flock to Rhode Island to hunt themselves some lions, and in the process meet and mingle with the northern liberals and bond over their common hatred of the threat from the dark continent. Partisanship is solved, and the American empire lasts another century on the backs of one billion taxidermied lions.
Pokemon win.
Alternately send Celebi back in time to grab Tsar Bomba after all the lions are in Rhode Island. The entire state falls within the "you are now dead" radius of that device, so all the lions perish in one fell swoop. Even if they're all sashed, burn/radiation damage gets their last hit point.
