NO WAR between countries has been ‘necessary’ for more than a hundreds years, but likely much longer.
That’s because sovereign countries technically don’t exist. They are corporations reporting to the cabal leadership, with governments effectively operating as criminal gang syndicates, selected by the cabal, NOT via your vote.
Most wars have been fought to divert public attention from government crime, limit our freedoms, enrich corporations and politicians, and launder money. – “Beach Milk” [on Gab]
