War Is Over...if you want it
The answer, I believe, lies in John Lennon's lyrics to this timeless anti-war song: war is over if you want it and I strongly believe that the reason we still have wars is because voters (especially in the USA) don't care enough to keep fighting for peace and not allowing administration after administration to trick us into thinking mass murder is justified because it is done in the name of fighting for our freedom. If we really, really wanted the war to be over, it could be.
The above video collage set to John Lennon and Yoko Ono/The Plastic Ono Band's classic Happy Xmas (War Is Over) is put together by YouTuber Sakitamasao. The song itself was recorded 36 years ago at the Record Plant Studios in New York City with the help of producer Phil Spector. The children singing in the background, who really add to the overall beauty and power of this song and who were fully credited on the single's sleeve and even pictured on its cover (above), were from the Harlem Community Choir and would all be in their forties now, having lived through many more US wars since the Vietnam War -- which was what the song was recorded in protest of at its recording back in November, 1971.
