the alies and access powers of ww2?

"The Allies were principally the United Kingdom, United States, France, USSR. Later, the British dominions joined (Australia, Canada, New Zealand and South Africa)."

I hope there are no old Aussie, Kiwi, Canuck, Saffer, Indian, Ceylonese, Burmese, Rhodesian, British West Indian, et al soldiers reading this. The entire Commonwealth was in from the start; the USA was the second-to-last country to enter the war (Brazil being the last, but in mitigation it was the only South American state to deviate from neutrality).

Furthermore, "Italy (who briefly sided with the Allies but switched sides halfway through)" gives the impression that Italy switched from Allied to Axis; in fact it was a signatory of the 1940 Tripartite Pact (along with Germany and Japan) and, following the overthrow of Mussolini in 1994, was able to offer only minimal assistance to the Allied forces.

You also do many of those South East Asian countries a disservice in saying that they fought for Axis/Japan. They were occupied, brutalised states, and the vast majority of those country's populations who fought for the Japanese did so unwillingly.

I presume you mean axis?

The Allies were principally the United Kingdom, United States, France, USSR. Later, the British dominions joined (Australia, Canada, New Zealand and South Africa). So did China, Belgium, Brazil, Czechoslovakia, Ethiopia, Greece, India (as part of the British Empire), Mexico, the Netherlands and Norway.

The axis powers were Germany, Japan, Italy (who briefly sided with the Allies but switched sides halfway through), Hungary, Romania, Bulgaria, Yugoslavia, Thailand, Finland, San Marino, Iraq, The Philippines, India (Provisional Government of Free India), Vietnam, Cambodia, Laos, and Burma.

Main Allies- America, UK, Canada, France, Russia/Soviet Union, China

Main Axis- Germany, Japan, Italy

There were a lot of countries on both sides, but these are the better known ones.

1) Axis, not access

2) It would be faster to Google it.
