No, but it honestly probably would have been if the Central Powers had won WWI. American entry into that war was made possible the sinking of the Lusitania, which was secretly carrying war munitions. There is some evidence that the British enabled the event although this is admittedly a minoritarian view among historians (last I checked). It was undoubtedly beneficial for the Allied Powers though.

The British Empire are pretty much the "bad guys" of world history insofar as such a designation makes sense. The punitive measures they arranged after WWI were directly responsible for the rise of the Nazi party in Weimar Germany.
