Referring to both ww1 and 2

UH... Italy and Japan were ALLIED with Britain and America in WW1.

Turkey allied with Germany in WW1 but stayed OUT of WW2 until Feb 1945 when the writing was on the wall and jumped over to the Allied side.

Basically the WORST nations to be allied with in WW2 were Japan, the Soviet Union (Russia), and Italy.

Particulary Japan that did NOT declare war on Uncle Joe in 1941 even though they told Dolf the Demented they would and the Sovs didn't declare war on Japan until August SEVENTH 1945.. The day AFTER Hiroshima was bombed and they were trying to grab a big old hunk of the pie that the guys who had been fighting for from 1941 were about to carve up.
